In my country (the UK), the penalties for driving dangerously due to being too slow are usually greater than the penalties for speeding. Being unreasonably slow could make other drivers more likely to overtake and have a head-on collision, or hit other cars when re-merging back onto their side.

Single-track country roads are the most problematic, though, as everyone has a different idea of what the safe speed is - and the limit is as high as 60 miles/hour! I wouldn't be against simply reducing the national speed limit for roads without markings to 30, so that at least then people could be reasonably expected to drive at that speed, rather than at an unspecified speed anywhere up to 60.

Most people have terrible overtaking skills, they sit too close behind the car they are going to overtake, are in the wrong gear and don't accelerate hard enough when they do go. Either that or are too timid and just sit behind slow vehicles causing a long tailback.
