Tesla had a lot to learn in
Tesla had a lot to learn in the beginning and more still. The X:s doors were overly ambitious, but over time things improved. The 3's ramp up was very ambitious and over time things improved. The S and X both had battery issues and the early S had failed drive units. These were growing pains
If you want to know how much you can trust Tesla today look at the Y and the upcoming Cybertruck. Those vehicles will be much better than the past. Early adopters take risks, you can always wait and see before you spend.
