without a car at all it would be even easier to turn around and look behind. But it would be silly, because, without a car, you wouldn't need to look behind while backing.
On the other hand, commuting with something the size of a small boat is a little difficult and inefficient, while moving all those space and weight in the traffic.
surely a very wide/high/long car is spacier than a smaller one, that's obvious, but there is a limit which is "how much larger" makes sense, objectively. And I think an Acura TL is better than something bigger for commuting comfortably in a sensed way.
To each his own then.
