True. A catalytic converter could get hot enough to light some grass.
Burned a few like that back when ..... Our sheriff recently chased a bad guy into CRP grass and burnt his SUV to the ground !!!
Fastest I’ve “ever” been on the ground was 203mph in a buddies vet he had built. Back road in Texas etc etc .
But have to admit some new vehicles these days are soooo smooth and quiet on good roads at high speeds. I was in my 2WD Tundra Crewmax and looked down at the speedo and was doing 100 plus comfortably .....
Now I use a Escort 360C radar detector with a “limit” setting of 75mph that alerts me when / if I’m speeding.....
Texas !
