I've been cycling all my life and (so far) never been knocked off. I commute once or twice a week just a short 3 miles each way. Recently the driving standards is getting worse (or I am getting less aware - who knows). Today two close calls involving and oblivious driver and a highly aggressive driver have made my mind up. I need a helmet cam. Does anyone have a recommendations? It is primarily a safety / show my point of view camera. I do shift work so cycle day and night. Don't want to spend more than £100 including sim card etc. Hope you guys can help me stay safe Cheers!
