Allow control of vehicles other than the 'active one'

[tckarenchiang]

Currently, only the vehicle in which the player 'sits' can be controlled.
We should allow all vehicles in the game to be controlled.
It should probably work like how AI vehicles are controlled by .lua scripts right now.

@tckarenchiang: did you mean to close this issue?

I don't believe #44 implemented this, does it?

I thought commit e82eae8 did it?

Can users now control multiple vehicles other than the one the player is in by publishing Twist messages to specific topics?

How would they address specific vehicles?

IIUC, e82eae8 applies the same Twist to all vehicles. That would be something else.

Not yet in the previous PR, yes, you are right. I got confused.

This will be fixed in the later PR.

Thanks for reopening the issue!
