Bug Description

When standing very close to transport vehicles upon getting commanded to get in, pilots sometimes don't promote the vehicle but will sit inside.

Very easy to see with helixes.

Helixes that just landed will never be promoted by pilots.
Helixes that have been fully stationary for a few frames will be promoted.

Reproduction Steps

In this video you can see that the first two pilots that got into the first helix didn't promote it, while the second helix was promoted correctly three times:
