My bicycle might not be as fast as your car but my life is worth more than the 5 seconds of your time it would have taken for me to exit that roundabout before blasting past and undertaking me. Learn some patience, your not as important as you like to think.
If I'm in the fast lane on the motorway, it's because I'm overtaking, which I was in the process of doing.
Don't go flashing your lights at me to get me to move over when I have nowhere to go to. I'm sorry my 5mph over the speed limit wasn't fast enough for you also.
