Yes, when you put it like that 1.1 seconds to react does sound scary, but think about what happens on the roads.
Most
drivers do not obey the two-second rule. If you do you are one of the exceptions (and overtakers will slot into the gap you have left

)
So as you're blasting down the outside lane at 80 mph, what is your reaction time if something goes wrong in front of you ?
That's right: probably 1.1 seconds or maybe even less.
Run into the back of a lorry and you'll be just as dead.
Also - unless you run out of fuel it is
very unlikely that the engine will stop suddenly, completely, and without any warning.
So check your fuel and your carb heat. Keep an eye on those T's and P's, and be ready and alert.
But don't get paranoid: it's much more dangerous on the roads !
