angle
is the perceived angle between the incoming and outgoing edges at the intersection. It can differ from the real angle because it does smart stuff like look further ahead down the road to understand where we're actually heading.
For the u-turn incoming/outgoing pair along the same edge, any changes in angle will always match, so the difference remains 0.
. This is the important assumption that by adding it here guarantees we always have a 0° turn in the intersection view.

Same comment as above. The other assertion is because we only manually insert here if we didn't above.

nit. probably worth passing road by const reference: I.e. const auto& road
Due to some rather complex logic that tries to calculate intersection angles by looking further up the road, it's possible to return an intersection view that is missing a u-turn - something which is assumed to exist in later guidance calculations. We apply a fix here by ensuring the u-turn is always included in the returned view.

Due to some rather complex logic that tries to calculate intersection angles by looking further up the road, it's possible to return an intersection view that is missing a u-turn - something which is assumed to exist in later guidance calculations. We apply a fix here by ensuring the u-turn is always included in the returned view.
Context
The full graphic details are in #6218
The motivation for this PR is to unblock the debug build on very large (i.e. global) datasets. Currently they will fail on this assertion, so we are unable to reach issues further down the processing chain.

Ideally we would refactor what looks like some quite brittle intersection code, but that requires:
so this appears to be the better alternative in the short-term.
