Which is a very sober and reasonable statement. If other companies deliver better value and quality, the only reason to buy a Tesla would be brand-loyalty (which is not a good reason to compromise on value/quality)
In my area, I can lease an entry-level Mercedes EV (I forget what they're called) something like 20-30% cheaper than I can get a Model 3. The entry-level Mercedes is decidedly worse than the Model 3, but you can't beat the pricing for what is still a very solid car (with more space and better sound quality to boot).
Congrats on coming to a conclusion based on facts rather than brand-image.
Rivian seems to have produced a good car, especially considering the young age of the company.
