For roadtrips, you're absolutely right.
The average car travels less than 50 miles on the average day though (more like 30 I believe). This means you don't have to charge except on roadtrips (provided you can park outside in the sun, and don't drive more than average. The battery can provide some smoothing out of day-to-day variability though).
Whether not having to plug in at home is particularly useful... hard to know if it's something consumers want.
If you are parked outside in the sun, you'll need to spend some amount of energy keeping the battery at a healthy operating temperature.
