Holy shit, you've just figured out how to add a whole nother layer to the personal transport equation. Mega parking structures as close to each destination as possible, but due to their size, they aren't in walking distance, so build smaller parking lots for golf carts within walking distance.
Then you drive your unnecessarily large vehicle from your suburbanite home to the big parking lot, walk to your designated spot in the golf cart storage lot (or pay to take the elevator), then drive your cart to the office or store lot.
But why stop there? Maybe the oversized trucks and SUVs are too big to be stored in a normal consumer-level garage or driveway. Maybe we should do golf carts on that side, too.
And to fully close the loop, make golf carts and trucks/SUVs support driving right into the driver seat with a mobility scooter. And give the scooters seats that recline to a lying position, have built in toilets, and waterproofing so they can go in the shower, and we can eliminate the need for walking entirely. Think of how much easier life would be if we didn't need legs!
