Probably for less time than it takes to charge a car - and many people eat whilst driving...
I never eat in my car. I don't have to clean up after if I don't do it at all. People in my family are also legendary for apologising profusely after spilling sticky, smelly everywhere.
No way. So easy to just stop for a few minutes.....whereas literally impossible to clean up milk-based things spilled onto the carpet. It reeks for weeks.
Also.....in reply to another comment about electricity, I'm ready for that. I make my own....and lots of it, too. Over 70kWh / a day at the moment.
This is all possible. One just needs to decide to do it......and build toward it is the cash isn't to hand today.
