Speedway: Sunset Circuit

The car starts at twice the previous base speed. Speed rises linearly with elapsed time to 10× the new starting speed after 180 seconds, then caps. Cars stay upright on the extended 2.5D road. Arrows/A/D or drag steer; Down/E/Brake slows; Space/Boost restores speed faster. Clocks add 7 seconds. Three crashes or no time end the run.
