208 Km/h is some speed to be driving.
But many common, even family cars have top speeds near or exceeding that.
AFAIK, in Ireland;
Double Deck buses are required to have speed limiters fitted and set at 64 Km/h, their maximum permitted speed.
Trucks are required to have speed limiters fitted and set at 90 Km/h, their maximum legal motorway speed.
Coaches are required to have speed limiters fitted and set at 100 Km/h, their maximum legal motorway speed.
Why are cars not obliged to have speed limiters fitted and set at 120 Km/h, their maximum legal motorway speed ?
