If you get cut up it's not by something behind, it's something which is now in front.

If somebody is tailgating you, you need to allow more distance to the vehicle in front to compensate for the driver behind not having the ability/reaction time to stop so quickly, especially in bad weather.

Also if you are aware that someone from behind is doing a dangerous overtake you can compensate for that too. I've had an incident when a driver tailgating behind did a stupid overtake into oncoming traffic and swerved into back to my side of the road early. If I hadn't have been watching my mirrors I would have been sideswiped as I had to brake to let him back in.

Very true, when possible I will never sit at the back of the queue.

Having just done a run to east yorkshire, on roads i have not been on before, through Halifax, Bradford Leeds and York (whose town centres are awash with information and direction arrows on two and three lane 40mph roads) i can say that the Riderscan was of little use. You needed all concentration on the road and quick glances in your mirrors to make sure you were in the right lane. The Riderscan does not give any view of directly behind you, and they do not claim it is to replace your existing mirrors, or the look over your shoulder to confirm what you see. It fixes to the windscreen with a powerful adhesive, i don't think anyone could steal it.As i said before, in my opinion, it is not worth the price and, does not improve your rear view any more than the little overtaking mirror i have on the right hand mirror( i got two for £1 at the pound shop).

These were in West Yorkshire when I lived in Bradford for 21 years, have I missed something?

He went TO East Yorkshire, from Lancashire, thus passing THROUGH West Yorkshire on the way, though I'm not prepared to think about differences between the former West Riding and the West Yorkshire Met County......

Ahh now I understand.

Can of worms best left unopened those county lines

Any device which distracts attention from looking in front is a bad thing imo.

Sorry that's not true, just ask the people who've been rear-ended by blind cagers whilst they've been sat at traffic lights.

Observation is single most important factor for safety, so anything that can improve that has to be considered.

Oh, that means at traffic lights I'll need to do a U-turn and face the direction I've come from in case I get rear ended and use the riderscan to see when the lights change...
It all makes sense now.

I agree with others the quick over the shoulder check always works for me.

Oh it works, but you have to look away for a short, but distinct, period, and at M-way speeds (when you really could do with a view of your blind spot), you can cover a lot of ground. Something like the stick on overtaker mirrors gives you a very wide view, and requires only the briefest glimpse away from the road ahead. Of course, there are times when an over the shoulder check is needed - look for tossers coming your nearside at roundabouts, or joining a dual carriageway where you need an all round view.

Certainly willing to be proven wrong but the IAM training I had always taught me to be very aware of your surroundings so you could comfortably & quickly make your shoulder check.
