Sticking to the speed limit does not make you a good driver

Last night I had a Ford Galaxy people carrier pull in front of me out of a petrol station.  This annoyed me a little, but i decided top give the driver the benefit of the doubt. 

However, my frustration became increasinly heightened as the driver was keen on doing 5 mph, and sometimes 10mph below the speed limit.  There was no need for this, the roads were dry, there was very limited traffic about. 

Next we came upto a roundabout, and they pulled into the lane to go left, rather than ahead. Thinking what was about to happen, i stayed back - and indeed they saw their mistake and pulled back into my lane to go straight ahead.

Again, they were doing 20mph in a 30mph limit, and I was starting to wonder how I was going to be able to get away from this driver before there was a simply monumental accident.  Next we came to a larage roundabout which was busy. This time in the right lane to go straight ahead of right, but with no signal they veered off to the right. A car coming the other direction wanting to go straight ahead had not expected them to do this due to lack of signal, and had to slam on their brakes to avooid a colision. The driver who I had been following made no reaction.

So before you judge someone who going too fast on the roads, please remember for every 1 of those peoploe who may be oing 1mph over the speed limit, there is someone who thinks they are the safest driver ever because they stick well under the speed limit. Not true!
