Other manufacturers are manage prices with consumer and dealer incentives. If you pay attention to car promotions, there's almost always a lot of differences in consumer cash back by model. Some manufacturers almost always have a baseline cash back, but if they want to raise prices, they can reduce that; if there's a model they want to move, it gets more, etc. Premium brands like to push leases and run promotions there. For the manufacturers with a captive finance company, there's even more room to play with pricing there.

I don't think Tesla runs promotions like that, so if they want to change the price, they have to change the price.
