I don't think it's that bad. The worst interiors I ever saw were circa-2010 Prius, but then again you get great fuel efficiency and a good shot at 300,000 miles with regular maintenance. Bolt has tradeoffs just like the Model 3 - not just the headrests - but it is a good car. Just happy there are EV choices and it's practical now. I'm grateful for every company that sells one.
It gets a mention quite a bit [1 as one of many examples]. I was kind of shocked at the forward-tilt and there's no way I could tolerate the car long term; likewise my sibling and a few others who tried it out with the intent of going all electric decided the seats were unacceptable. This is the passive version of anti-whiplash changes.
