Tesla is not a good learning car/first car for a number of reasons -IMO.
Not to mention, it will likely be damaged, which could be expensive unless you don’t care about dings, etc.
Not sure how old your kids are, but if you can, I’d get them their own cars, like a used Honda accord or similar. The accord gets good gas mileage, it’s safe, big car, handles well, lasts forever. They will have that car well into their 20’s hopefully before finally buying their own car.
My 19 year old has a 2012 accord 5spd 4cyl that is a blast to drive, safe, reliable, big. She loves it. She learned on it and then got it, more or less, at 16.5 or so. She knows how to check the oil, tire pressure, change light bulbs, other basic maintenance . We just put an Apple car play stereo and speakers in it for her for Xmas and it’s like a new car now. She uses accord at college, to get to/from home, etc. Unfortunately, there’s no e car chargers at NDSU in the dorm parking lots so any electric car would be impractical. I’m sure that’s the case at most colleges, so maybe something else to consider.
Plan to buy accord or similar for the 13 year old in a few years.
