Boiling brake fluid on the street is really really hard, though I guess I could see someone doing it in a Tesla Plaid (it has similar sized rotors to my car, but has 2.5x the power and 1.7x the mass).
The price different between cheap DOT3 and cheap DOT4 is so small it doesn't make sense to buy DOT3 at all. Upgrading to a basic DOT5.1 or a premium DOT4 like ATE is an extra 10 dollars that probably doesn't need to be spent on a road car though.
