If we all feel like we need a car on-demand to get where we need to go in Grand Rapids (when it's further than a bike or foot, anyway, or maybe you don't want to bike given your attire), and Uber/Lyft/SteadyFare are successful alternatives but you desire autonomy... why not offer a car that you can hop into in your neighborhood, pick up other people on your way to your destination (keeping an eye on their ratings to be sure you could "trust" them) and have it offer you discounts as you pick them up (or you could avoid the discount and keep it to yourself), you get to your destination and there's designated zones in the major districts that these cars are automatically able to park quickly and easily (no parking issue), and the vehicle just keeps moving on and on to the next person.
I have my car to get me to kiddo drop-off in the morning, sometimes to go to lunch, sometimes to go to client meetings, and then to get home. But I live a mile from work. My company pays for parking in a nearby lot for my vehicle - but my car sits idle for 8 hours of the work day. Then I get home and my husband or I pick which car to take to go out for the evening. We're rarely out separately. But we maintain two vehicles because we go to two separate job sites, we pickup baby on different schedules (he picks up earlier than I'm out of work, while I drop off later than he goes in), and one of our vehicles is the towing car for our camper. We used to have scooters that drove 35 mph - perfect in the city. But there's SO FEW designated scooter parking areas downtown that you'd drive all over on those seeking a spot to park - or park illegally. Nevermind that every single time I was out, I would have someone (usually in a truck) roll down a window and yell something inappropriate at me, threaten me to move with their vehicle, or generally intimidate me despite going the speed limit and driving closest to the center of the road exactly as you're supposed to on a motorized scooter.
