Tesla does: https://futurism.com/the-byte/tesla-wildfires-bioweapon-defe.... It's an optional upgrade. I ordered it for my Model S because, at the time, Hawaii was experiencing really bad VOG, which my girlfriend was extremely sensitive to. On bad days, she could retreat to the Tesla, activate BioWeapon Defense mode, and experience some relief.
I mean... a good respirator is like $30-40. Significant savings over a Model S, and you're not stuck in the car. But I suppose wearing a mask can be uncomfortable.
You can take any car to a racetrack and drive as fast as you like for a couple of hundred dollars per event. You can even get professional instruction.
those events do not let you go as fast as you like.
there ARE some events that do but its a really bad idea in a car with no cage and safety equipment.
I've found that my stomach for speed is inversely proportional to how fast I'm allowed to go. I'm not sure I have the stones to go fast enough to need a roll cage on a race track.
Same goes for off-roading. Luckily I live like an hour away from a big parc in Germany so my 1982 Range Rover can enjoy his natural environment at least a couple of times! Logically totally useless, but hell of fun!
