Cannot pull players from vehicles

I play cop, some of the time you flat out cannot people out of vehicles (while restrained in PD etc) but have also seen this in public (there was someone who was kidnapped and they couldn't pull him out so we had to and it worked for one of us).

I've heard of others complain about this and have had it happen personally 5 times or so, end up just storing the vehicle to get them out.

edit: After speaking with James32, the function that stops restrained people ejecting -kind've works-, we'll ask them to jump out when we get back to PD and are stationary, sometimes it works, some times it does not so we store the vehicle to get them out (very problematic with other peoples vehicles at banks etc)
