Driving forwards is easy. Reversing is... weirdly much trickier. This video from Minute Physics explains why you shouldn't feel dumb about it -- because it's all down to physics working against you.
Drive forwards and you turn the wheels right there with you at the front, changing the direction you travel in with the rear wheels simply following along. Reverse, though, and you turn the same wheels but it's the rear ones that lead -- which is, as this video points out, an unstable system that can mess up very quickly. But words don't do a very good job of describing this phenomenon, so watch the video. And then feel better about your awful bay parking. [Minute Physics]
