That's the thing though, I couldn't care less how ineffective they would be today. They were pure, simple and visceral. You had to drive them with guts as it was probably trying to kill you every corner, and to go fast, which you could also do in a crap car, you had to go over the limit.
Now, it's more of the same. They all have to drive the same because the cars don't permit anything else, the only place where you can prove yourself is in overtaking, and they are slowly killing that aswell. If you have a crap car today, you're doom because you can't get that extra bit... It's not because it's tougher, it's probably not (Except maybe for the G's), but because they're just killing any creativity a driver would need to go where he isn't suppose to go. It's all just a big show where everyone is suppose to finish where he should, and where slower cars are encouraged to stay behind.
