then how do some ppl get 2 demerit points for driving 10km to slow?
if the max is what ur suppose to be driving then why do ppl get tickets for driving 10 below?? its a grey area
Think in terms of making safe lane changes when vehicles are going significantly faster than you, think about the traffic backing up as a result of someone disrupting traffic flow (and all of the ancillary issues that causes, such as increased odds of collisions, disruption to emergency vehicles on clogged roads/highways, etc). Then you have the aggressive morons who deserve tickets as well, who endanger you (the one going slow) as well as themselves and others by tailgating and cutting you off, rapid/aggressive lane changes, and the stop-go effect it has on the rest of traffic.
I tend to think of traffic as a single organism with moving parts that need to be in harmony and in tandem with everything else within it. 50% defensive and 50% offensive driving is required.
