Michigan → New York · Interstate 75 / Interstate 94
Coming back from Detroit, Michigan, to Buffalo, New York, the return leg also clocks roughly 409 km (254 miles) typically along Interstate 75 / Interstate 94, but the traffic picture shifts considerably compared with the outbound segment. Detroit, the Motor City and historic capital of the American auto industry, fades behind the wheel while the vehicle pushes back toward Buffalo, the western New York gateway to the Niagara Frontier and Lake Erie, often after a full day of meetings, site visits, or prospecting calls. Plan 3h 54m plus a generous buffer against evening congestion, particularly on Fridays, holiday eves, or after major sporting events. Driver fatigue is the dominant concern returning home; mandatory rest breaks every two hours are non-negotiable. Fuel spend on the return stays near $34.22 for 37.2 liters (9.8 gallons). The corresponding reimbursement on the way back reaches $175.87 at $0.43/km. Combine both legs on a single Clara receipt to document the full round-trip cleanly, with separate timestamps for transparent audit defense.
