This has probably been discussed to death years ago.
For HLVC type 1 (hitting a wall), it would be nice to have closing speed, like OBH and CON packets do. It does have vehicle speed, but it's the speed after hitting the wall, and I always get the MCI packets first so I can't easily judge the impact speed.
OR
It would be nice of OBH could be triggered for hitting any solid track feature, instead of only layout objects.
Is there any way that reliably works to detect how hard a wall hit is? For years we have just compared speed in MCI packets, which kinda works but is a bit crude with due to position prediction .
