This has been suggested several times during the past year and I am quite surprised that nothing was done on this matter. The idea is simple: Adding a padlock icon above any vehicle which can welcome passengers when this one is full or is locked by the driver via the vehicle control interface (lock / squad restriction). The purpose is quite logical: to avoid that any player who wish to enter a locked vehicle, runs after it again and again and finally realizes that he cannot enter inside. Very frustrating isn't it? With this simple add-on, we could avoid more friendly fire from angry infantry and we could avoid more team kills because of road kills.
