Super Cruise, which is arguably better than what Tesla has, costs $25/mo.
Tesla’s $200 monthly price is probably there to make the $15k upfront price look like a better value, for people who don’t compare to the competition. Tesla seems to have a lot of pricing power because people really want a Tesla in particular.
Super cruise requires a very high end trim to even purchase the super cruise package. You can get FSD on the lowest model 3 specs. FSD is ridiculously priced though, it’s just not a reasonable comparison on the monthly fee.
Super Cruise on the Bolt EUV is not comparable to Tesla Enhanced AP or FSD. It can't even change lanes for you, you have to manually do it[1]. It also is restricted to a specific set of highways. It's comparable to Tesla's basic Autopilot, which is included for free with all Tesla models and has no subscription required. Super Cruise at least for Chevy EV's is traffic aware cruise control + lane-keeping + driver monitoring, that's it. Tesla's are still more expensive than the Bolt though, there's no question about that. But Chevrolet also had to recall every single Bolt ever made due to battery issues [2], including 2022 models. So I can't imagine anyone is in line to actually buy a Bolt now. Many parking garages even have signs that say you can't park there with a Chevy Bolt.
