Tesla? No. BEV as a daily driver? Most definitely.
1) I have a friend who lives in Tooele and works in SLC, and he bought a used Fiat 500e to use as his commuter. He, too, has free charging at work and generally never charges the car at home. He's been commuting like this for years. Moral of the story: you don't need a Tesla--or any BEV with 250+ mile range--for this use case.
2) Having 240v charge capability ("Level2") at home is a big plus, as it can greatly expand how much you use the car. After a morning of running errands, for example, you can come home and plug in for an hour or two while you have lunch and do other things, then head out for round two of more errands. I rarely used my Level2 charger at home, but when I wanted it I was very glad I had it.
3) Driving for free (ie, not paying a penny for the 'fuel' your car uses) is extremely addictive. So are the numerous advantages of a BEV over any gas-powered vehicle. Once you get used to the quiet, the immediate throttle response, the instant heat, the near complete lack of maintenance, etc, when you hop back in a gas car it suddenly feels so... old.
I say go for it.
