OMG I bet some crazy person buys me one fro Christmas! Personally I would rather turn my head and have a look - lets the drivers know that you've clocked them too and you can ask them to slow down if they're going a bit fast
personaly i think its a brillient idea, being an old crock and still wanting to ride, i have lower back pain and even though riding has greatly strenthend it i still find it difficult to turn and look behind......dont worry it will all come to you with time...take the p155 if you must
I actually agree 100%! There are plenty of us out there you know who really struggle just to ride, & anything like this can make life just a tiny bit easier! Yes, I know its hilarious, but I can only echo the previous poster - it comes to us all! ( & as my own difficulties are the result of years of breaking in, sorting out other peoples equine mistakes & a few falls XC & Pt to Pt I'm not ashamed of it!).
