OP: Look at it this way if they are going slow they are not going to crash into you when you are giving way at a junction or roundabout.
The amount of cars I've seen in my village coming up to junctions and skidding when they are already at walking pace is stupid.
Be safe, not sorry.
this is true, however im pretty sure a lot of the time people who have analysed the weather i saw to be 30mph might also not realise that planting there foot firmly on the brake to slow down in conditions similar to what you must be experiencing is a bad idea.
But i see what you're saying for sure.
