Lift problems are often about the
large number of safety interlocks, and I'd expect one on the escape
door on the roof of the lift car too.


Do escape doors on the top of lift cars exist outside Hollywood?

Yes they do, but they tend to be locked down in public lifts. The few that I
have seen, have a switch sensor on the panel, that triggers an alarm and
cuts the motor as soon as it is opened. I triggered one once by accident at
university (many years ago) when I knocked the ceiling panel, and it opened
:-( Luckily, the lift reset itself when I closed it again :-)
