Summary of Significant Accounti

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation The unaudited condensed consolidated financial statements include the accounts of the Company and its controlled subsidiaries. Intercompany balances and transactions between the Company and its controlled subsidiaries have been eliminated. The preparation of these unaudited condensed consolidated financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the amounts reported. Actual results could differ from those estimates. The information included herein should be read in conjunction with the Annual Report on Form 10-K/A for the year ended December 31, 2023. The condensed consolidated balance sheet as of December 31, 2023 included herein was derived from the audited financial statements as of that date but does not contain all of the footnote disclosures from the annual financial statements. The unaudited condensed consolidated financial statements reflect, in the opinion of the Company, all adjustments of a normal, recurring nature necessary for a fair statement of our financial position, results of operations, and cash flows for the periods presented but are not necessarily indicative of the expected results for the full fiscal year or any future period. Risks and Uncertainties The Company’s operations are principally funded by available liquidity from cash, cash equivalents and investments. Management expects to continue to incur operating losses and that the Company will need to opportunistically raise additional capital to support the continued development and commercialization of the Aurora Driver. Management believes that cash on hand and investments will be sufficient to meet its working capital and capital expenditure requirements for a period of at least twelve months from the date of these financial statements. Management will continue to evaluate the timing and nature of discretionary operating expenses, as necessary. Financial instruments that potentially subject the Company to concentration of credit risk consist primarily of cash, cash equivalents and investments. The Company primarily maintains its cash and cash equivalents at U.S. commercial banks, while its investments primarily consist of U.S. Treasury securities as well as corporate bonds and commercial paper. Cash and cash equivalents deposited with domestic commercial banks generally exceed the Federal Deposit Insurance Corporation insurable limit, though the Company has not experienced any credit losses on its deposits. The Company is dependent on its suppliers, some of which are single or limited source suppliers, to design, develop, industrialize and manufacture components, and these suppliers may not produce and deliver necessary and industrialized components at prices, volumes and on terms acceptable to the Company. For instance, the Company plans to rely on a single supplier, Continental Automotive Technologies GmbH, for the production, provision and full lifecycle support of its future generation of the Aurora Driver hardware system which will be integrated with OEM platform vehicles. In instances where the supplier fails to perform its obligations, the Company may be unable to find alternative suppliers to satisfactorily deliver its products, if at all. Recent Accounting Guidance In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2023-07, Segment Reporting, which expands disclosure requirements for reportable segments including enhanced disclosures about significant segment expenses. The updated standard is effective for the Company’s fiscal 2024 annual period and interim periods beginning in the first quarter of fiscal 2025. The Company is currently evaluating the impact of this guidance, and expects to adopt the standard during the fourth quarter of 2024. In December 2023, the FASB issued Accounting Standards Update 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires disaggregated information about a reporting entity's effective tax rate reconciliation as well as information on income taxes paid to enhance the transparency and decision usefulness of income tax disclosures. The updated standard is effective for the Company’s fiscal 2025 annual period. The Company is currently evaluating the impact of this guidance, and expects to adopt the standard for our annual periods beginning January 1, 2025.

Summary of Significant Accounting Policies (Policies)	9 Months Ended

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The unaudited condensed consolidated financial statements include the accounts of the Company and its controlled subsidiaries. Intercompany balances and transactions between the Company and its controlled subsidiaries have been eliminated. The preparation of these unaudited condensed consolidated financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the amounts reported. Actual results could differ from those estimates.
Principles of Consolidation	The information included herein should be read in conjunction with the Annual Report on Form 10-K/A for the year ended December 31, 2023. The condensed consolidated balance sheet as of December 31, 2023 included herein was derived from the audited financial statements as of that date but does not contain all of the footnote disclosures from the annual financial statements. The unaudited condensed consolidated financial statements reflect, in the opinion of the Company, all adjustments of a normal, recurring nature necessary for a fair statement of our financial position, results of operations, and cash flows for the periods presented but are not necessarily indicative of the expected results for the full fiscal year or any future period.
Risks and Uncertainties	Risks and Uncertainties The Company’s operations are principally funded by available liquidity from cash, cash equivalents and investments. Management expects to continue to incur operating losses and that the Company will need to opportunistically raise additional capital to support the continued development and commercialization of the Aurora Driver. Management believes that cash on hand and investments will be sufficient to meet its working capital and capital expenditure requirements for a period of at least twelve months from the date of these financial statements. Management will continue to evaluate the timing and nature of discretionary operating expenses, as necessary. Financial instruments that potentially subject the Company to concentration of credit risk consist primarily of cash, cash equivalents and investments. The Company primarily maintains its cash and cash equivalents at U.S. commercial banks, while its investments primarily consist of U.S. Treasury securities as well as corporate bonds and commercial paper. Cash and cash equivalents deposited with domestic commercial banks generally exceed the Federal Deposit Insurance Corporation insurable limit, though the Company has not experienced any credit losses on its deposits. The Company is dependent on its suppliers, some of which are single or limited source suppliers, to design, develop, industrialize and manufacture components, and these suppliers may not produce and deliver necessary and industrialized components at prices, volumes and on terms acceptable to the Company. For instance, the Company plans to rely on a single supplier, Continental Automotive Technologies GmbH, for the production, provision and full lifecycle support of its future generation of the Aurora Driver hardware system which will be integrated with OEM platform vehicles. In instances where the supplier fails to perform its obligations, the Company may be unable to find alternative suppliers to satisfactorily deliver its products, if at all.
Recent Accounting Guidance	Recent Accounting Guidance In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2023-07, Segment Reporting, which expands disclosure requirements for reportable segments including enhanced disclosures about significant segment expenses. The updated standard is effective for the Company’s fiscal 2024 annual period and interim periods beginning in the first quarter of fiscal 2025. The Company is currently evaluating the impact of this guidance, and expects to adopt the standard during the fourth quarter of 2024. In December 2023, the FASB issued Accounting Standards Update 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires disaggregated information about a reporting entity's effective tax rate reconciliation as well as information on income taxes paid to enhance the transparency and decision usefulness of income tax disclosures. The updated standard is effective for the Company’s fiscal 2025 annual period. The Company is currently evaluating the impact of this guidance, and expects to adopt the standard for our annual periods beginning January 1, 2025.
