I can assure you there were many worries when my '94 V6 Exec approached 200km/h. Aside from the engine feeling like it was going to throw a rod, the amount of air being trapped under the car meant the front wheels felt like they were barely touching the ground. I also aborted at ~190km/h when I considered that if I couldn't see an obstacle coming some way past the horizon, the feeble brakes were never going to stop me in time. I was a "sensible" 19yo.
More seriously,
@HamboCairns while speed limiters are not inherently bad, they are a shit solution when governments solution for everything (poor road surface, too much roadside advertising, bad or missing signage, drunks falling onto the road because liquor laws aren't policed and no pedestrian barriers on high pedestrian traffic urban "nightlife" roads, etc etc...). Artificially lower speed limits reduces the driver's perceived danger of the road, which leads to either drowsiness, inattention or both.
