Sure, this is largely true (panniers and trailers not withstanding), but most car trips aren't to the store. I suspect the majority are to/from work/school. If we enabled more people to bike for our commutes and just use a driverless car (or a taxi/Lyft) for shopping, car ownership would be much less essential, and car rush hour would be a thing of the past. I just hope they put a bike rack on the Cruise cars. :-)
