Refers to which service is most widely used (miles or number of trips per day), so not a quality measure.

Refers to trips with humans in the vehicle. E.g. deliveries by self-driving cars are not what I'm going for here, and I will do what I can to disentangle these from human trips where possible.

Has to be entirely self-driven. E.g. Tesla with steering assistant, but that needs a human driver at the wheel, would not count.

Resolves subjectively by me in Q1 2026, according to the best possible sources (bettors are free to help me find them). Might be obvious at the time, or call for best judgment.

I will not trade in this market.
