i doubt this is true; most non tesla cars actually look good where is tesla looks like a dumpster fire... and don't get me started on how garbage tesla interiors are.
Unfortunately, it's pretty true at least internally, though their dumpster fire reputation is changing that. I've worked at a number of Tier 1 automotive suppliers and OEMs, and I can't even tell you the number of times I've had to listen to "We should do 'thing' because that's what Tesla does". It's leading to a lot of shitty and anti-consumer practices, but fortunately I think some of the smarter leadership is finally seeing that they were shitty ideas all along, and was nothing more that techbro bullahit.
