Thanks for clearing that out. I still think it is better to map for the
99.99% of drivers who need to follow the law strictly. Special tagging
for different emergency vehicles could be applied.

Just to be clear, I'm not advocating that legal separation MUST lead to
way separation. Just that a rule that wouldn't allow it would be a very
bad rule. What makes most sense based upon the ground truth should be
followed.
