The bed is pointless for commuting, but so are the back seats in any of those other cars.
I commute in a Fiesta, and it’s been years since anybody has sat in the back seats.
I’m a two-car household with my partner, but I’ve assumed that if one car is out of commission, we’d be fine with Uber+one car for at least several months while we take the time to thoroughly research/negotiate/etc. options.
