UK motorway junctions are all equipped with long sliproads. Generally you're supposed to do all your accelerating or braking on the sliproad when you join or leave the motorway, although traffic conditions can obviously prevent this. With that said, in free-flowing traffic, it can be incredibly dangerous when people fail to follow this protocol, and I often wish there was more enforcement.
