You guys drive backwards to us. So you'll have accelerator, brake, clutch. Your right foot should be next to the clutch, while your left foot does the accelerating and braking. Your left foot should be doing more work, so if your right lace is coming undone more, you probably have a fucked clutch and need to get that fixed.
I don't drive, but I can figure out what's wrong with your car based on shoelaces. How am I not famous?
