The power:weight rule, while good in principle, is a farce in reality. How many of you here have been booked for driving under this rule, but you still have the keys to the "too powerful" car? All that has happened is you have had to part with $135 or so. How does that contribute to road safety? It doesn't; it simply contributes to the state's coffers.
You can still learn in one of these, because a fully licenced driver is "in charge" of the car. But tell me, who is "in control" of the car? And while you can learn in one, and do your test in one, YOU CANNOT DRIVE IT HOME!!!!!!!!!!!!!!!!!!!! Because it is a restricted vehicle for P-platers. How freekin' stupid is that?

If you back up your argument with sound logic, the teacher cannot (in theory at least) mark you down in any way. After all, this is a democracy, and we are allowed to have opinions different to the rest of the population.
