Comment:

 This is a bug in the original which our timing fixes and workaround don't
 yet address. The same thing happens in DOS. It's a regression in the CD
 version. The root cause is that SCI games changed how the Speed setting
 worked in between SQ4 floppy and CD, but the Skate-o-rama scripts weren't
 updated for the change in the underlying components. (A common theme in CD
 regressions!) The scripts specify delays in game cycles, which in floppy
 was relative to game speed, but that's no longer true in CD. Game speed
 now only affects how fast you and other actors move, so you now have a
 fixed amount of wall-time to get away from the police, and it's not long
 enough to do so if ego is moving at medium to slow speeds.

 The good news is that this is fixable, the bad news (for me) is that this
 is a can of worms that isn't particularly fun, as I keep finding more
 little problems with this scene, and am revisiting the need for our
 existing workaround, but we'll get there eventually. Other good news, I
 just saw that New Rising Sun patched this (of course!) in a way that jives
 with my understanding of the problem, so that's encouraging. I love prior
 art!

 Renaming this issue to reflect this.
