Sidecar should avoid dangerous nav suggestions when an easier one is available

As you can see here, Sidecar is suggesting I take the upcoming left turn to get onto the highway when the very right side has an onramp to the same highway for the same direction. The distance taking the onramp may be slightly higher but is much safer and would not potentially obstruct traffic.


Start with the linked Google Maps route and screenshot to understand the unsafe left-turn suggestion. Trace where Sidecar chooses between route options, then verify that an equivalent, safer onramp is preferred when available.
