Yes it can be done. We have a car and 2 carts inside the garage. We have suv but not a big car.

Depth
 

Got me curious enough to go out and measure our garage depth. Over 19 feet on the car side. Looks like I'd want 8.5 feet minimum per cart. 17 is less than 19. Looks like it would be doable for this anecdote.

No. I have a 15’ RAV4 that’s fits ok with a bit of room to spare front and back but the standard sized golf cart just squeezes next to it. A tight fit.

I did it during a hurricane with 2 smaller carts. the issue is the HVAC unit on the pad on the one side because it limits the forward space. But it required me to basically climb out the car window and go out the garage door and use the front door.

No. I have a patio villa.

Our Par Car and Yamaha electric carts fit next to our Cadillac.

Unfortunately no.
