"Lane changes" aren't really much of a thing in the UK either. Firstly, in the UK they aren't 'equal' lanes. They are for overtaking only. Undertaking is illegal. So we don't just change lanes willy-nilly. We change lane to overtake someone, and then change back. Secondly, only motorways and dual-carriage ways are multi-lane. Most roads are single lane.
