Whether you agree with a law (and a speedlimit is just that) or not is irrelevant, you still have to follow it. The advantage of average speed cameras for you (and me), the speeder, is that your average speed is likely to be lower than your top speed.
If you're going to lose your job along with your license, maybe you shouldn't be breaking the law in the first place...
Now, I'm going to have to admit that the day I can't speed anymore will be the day I stop enjoying driving. That being said, I still prefer these over the single-point cameras.
We have average speed checking systems here in the Netherlands, and it just works on averages. They pick stretches of road that don't have the opportunity to stop, or leave the road, and take your average speed. So, if the limit is 60, you drive 80 for the first half, realize you're being clocked, and drive 40 for the second half... no ticket.
To be honest I find this system better than the single-point checking systems that are also widely in use everywhere.
