Have you actually looked whether the other manufacturers don't have issues with working conditions?
I had to buy a new car recently, and was thinking about electric and Tesla was one of the potential options.
I ended up buying a RAV 4 Prime instead. I do most of my driving within the EV only range of the vehicle, but it leaves me flexibility for road trips when needed. Eliminates the range and charger infrastructure concerns entirely, but I've also only had to fill up the gas tank once on the vehicle in the last 6 months.
Maybe there will be an EV that will directly out-compete on all those categories, but I think they've got competition coming at them from pretty much all angles.
But I don't care about the superchargers (I have a 2nd non-EV).
If you ignore that feature, the Nissan Leaf and Chevy Bolt are both cheaper and slightly more functional (hatchbacks).
Props to Tesla for pushing the chargers - EVs have benefitted - and now with Superchargers opening up to non-Tesla + other charging stations building out - the distinction will soon be minimal.
Genuinely curious, last time I checked everything non-Tesla was severely compromised somewhere.
