Scraping pedals. That's a matter of pedal clearance and pedaling while cornering. If you race, it can be a buig deal (especially for criteriums and on the track). For the rest of us, it is usually just a matter of learning when those pedals hit and coasting before we get there.
Three factors add up to determine when pedals hit: How high the bottom bracket of the bike frame is above the road, how wide and low your pedals are and how long the cranks are. Looking at each of those separately:
The bottom bracket height is a function of the frame design and how large your tires are. Non-racers rarely change frames just to get better pedal clearance; we just learn to live with it. (I've had bikes where I hit routinely. I consider pedal appearance to be expendable. Aluminum cleats step on the tops, bottoms get scuffed by roads. In other words, well ridden pedals look it.)
Pedal width: There is a lot you can do here. Platform pedals are dome of the widest and worst for pedal clearance. SOme of the clipless are so small that your shoe and foot dictate the clearance, not the pedal. But there are strong reasons to go to the pedal system that will work best for you in terms of foot comfort, locking and unlocking system,, etc. Pedal clearance is seldom the driving factor except for some racers.
Crank length: This is so related to your pedaling style and efficiency that pedal strike should never be the driving force (although one may choose the smaller of tow options if it is 50-50). An exception I made was when I was riding a bike set up as a fix gear that had a very low bottom bracket. I used the 170 length cranks that came on it instead of the 175s I ride on every other bike and still hit the pedals almost every ride.
All this said, look at your pedals. Will striking them gamage them? If yes, be more careful. SOme pesals have pressed joints at the corners that wil loosen up with enough strikes. Others you can grind away for years. Also, keep in mind if you change things that hitting a pedal on a bike the strikes pedals early is no big deal. Hitting one on a bike with a ton of clearance means you are leaned way over and it IS a big deal!
Been there, done that (all of the above!)
