Just got back from my four hours of "death by powerpoint" for having been caught by a fixed camera doing 35mph in a 30mph zone. Anyway, two questions arose from the course. First of all the instructor suggested that we boy racers should drive through 30mph zones in third gear because it will slow us down "but won't use up any more fuel." So, does driving at 30mph in third in my CTDi-engined Civic (at about 24-2700 rpm) use no more fuel than driving in fourth ? Second. It was stated that the big white "SLOW" sign painted on the road is only put there when someone has been killed. True, or urban myth urine-take? (Edited for shouting in the title and putting extra 0 in the rpm, mong!).
