I had a nasty accident cycling home last night when a chap in a car decided to overtake me then cut in front of me to turn left. I didn't have a chance. I was going about 20 mph and I smashed into the back end of his car, taking a nasty tumble.
Police came and I was taken to hospital in an ambulance - CT scan was clear so thankfully I have nothing more than a very bad headache and scratches and bruises.
The chap drove off, someone chased after him and brought him back to the scene. He didn't have a clue. He said he couldn't see me which is absolute tosh - it is obvious he had no judgement of speed/distance.
SO - for cyclists, make sure you wear helmets. Mine saved my life according to the doctor, it's now in two bits.
For car users - use BOTH wing mirrors. Most just use the right hand one and don't think to look out for cyclists. We have just as much right to the road than you do.
