I'm curious about how "relaxed adherence to rules" will be implemented.<p>If you're merging from an onramp into the rightmost lane of traffic, you'll get in either in front of someone or behind someone. Meanwhile, the merge lane that you're in is narrowing.<p>Say that after the merge lane disappears, there's a nice, fat shoulder, divided from the highway by a white stripe. You're not supposed to cross that stripe.<p>If things go wrong, you might sometimes elect to continue on into the shoulder, and then merge. Or you might just stop in the merge lane, which has its own problems.<p>So, if traffic is thick and stubborn, will an autonomous vehicle stop in the merge lane, or continue into the shoulder?
