Just watch out for the silly errors. I've seen many a rider unclip on the right and fall over left (or vice-versa). I've seen someone unclip, put his foot down, and then have the cleat slide downslope on the crowned road until he was doing an uncomfortable split over a downed bike. The safety unclip is useful (I do that one myself most of the time) - I've come to a stop and found that my cleat was stuck only to awkwardly fall in slow-mo. It's always good for someone's entrertainment when you do that at a busy intersection.
