As a matter of interest, in Countries where it is illegal to turn across a solid line, for there to be a junction without a break in the line? I have driven in a lot of European countries and have noticed that there are gaps in solid lines for every driveway. I have never come across a situation where a turn is prevented by a line. I suspect we would need more of the new tags to allow a turn, than just use an existing turn restriction where needed. This proposal would also need routers to understand the law in different countries. In the UK you are allowed to cross a solid line if you are turning, and it is common for the lines to be continuous across the junction.
