This is an odd comment considering how humans have lived hundreds of thousands of years without cars, and only a few decades with them. You’re saying that a solution that’s as old as time - and used by billions of people today - is not as realistic as a technology that hasn’t been developed yet?

We've had wheeled chariots and carts powered by animals for almost as long as we've had civilization (about 5000 years). Cars and trucks are simply more efficient (a defensible statement... https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5102965/ particularly with electrification), self-propelled versions of these.

So absolutely we will have cars and trucks well after we're able to develop driverless versions of them.
