I've been cycling pretty much daily recently, and only driving about once a week. This has had a noticeable affect on my perception of risk when driving. For example, I was absolutely certain a car was going to pull out in front of me & cause an obstruction this morning, but because I was in a car & not on a bike, the driver stayed put. I also get more irritated with certain women drivers who have no discretion over use of the accelerator, or concept of stopping distances. Full speed ahead at all times whether they are on the phone, checking the lippy, or not, and a one-size-fits-all 20 feet stopping distance at any speed, be that 20mph or 60mph.
