I disagree on the allowed u-turns with dedicated left turning lanes.
In Kitchener, we have an LRT and u-turns are restricted unless explicitly allowed. Examples are here and here. The former has a dedicated u-turn lane and the latter has signage visible on SV allowing the u-turn. What your describing with your examples is a requirement that has a dedicated left-turn lane AND a rapid transit conveyance. The rapid transit doesn’t really matter. If we removed the rapid transit, we’re left with a dedicated left turn lane so why can’t that configuration be allowed to do a u-turn?
We can have this discussion with the wider group if you would like to make a post in Discord. Happy to chat.
