I can see how an ad could pay for a visit to a web site, but how can you get an advertiser to pay enough for ads so that they pay for a few miles worth of power for a car (let's assume that it's an electric vehicle), plus a few miles worth of depreciation and maintenance?
The IRS currently allows a deduction of 57.5 cents per mile for business use of a vehicle. That's a ballpark figure for what the fuel and depreciation costs per mile.
I doubt that an electric car is that much cheaper per mile than a gas vehicle, since the battery is very expensive and needs to be replaced after some number of charge/discharge cycles. For a car that's used as a taxi 24 hours a day, you probably have to recharge daily, leading to frequent battery replacement. (A taxi can easily drive hundreds of miles every day - one round trip from midtown Manhattan to JFK airport is around 30 miles).
Even an electric self-driving vehicle requires periodic replacement of tires, shocks, etc. And a vehicle used by the public would probably require at least a daily cleaning of the interior. Plus, you're legally required to carry liability insurance (for damage you cause to other vehicles, people or property). Adding up all these expenses, it doesn't seem possible to break even by selling ads.
