I am new with clipless pedals so for me I really think about it.
What has me worried is in a few months when I'm not "thinking" about it anymore that will be the time I will fall.
Last weekend I was climbing a 4 mile hill & I had to stop to rest, the only problem was every time I would try & unclip I couldn't because I needed to keep pedaling to keep from falling over. Now that was a weird situation for me, I finally was able to get out & stop, but I thought for sure I was going over.
