For example, the seats on Tesla’s are amazing compared to OEMs that all outsourced something so fundamental to the driver experience.
If every OEM outsourced to Foxconn, that sounds like a race to the bottom. This worked for android because everyone in the world needs to own a phone, this isn’t true for vehicles.
Would you buy an ILove2Life EV200X? It claims to have better range than a Tesla Model 3 and it costs 25% less. It also has cool features like UltraBass speakers built into the headrests, whoa! When people buy a car, they usually expect it to last them at least 5 years, and they expect it to be in good working condition when they sell it (otherwise there would be no buyers). That's hard to do with zero brand trust.
Also you have the alternative to buy from other more reputable OEM - better fittings, but same core.
Second, savings on a vehicle aren’t comparable to savings on a phone.
I only wish Tesla has thigh extension. Otherwise the seats are really comfortable.
