[SPAWN PREVENTION] Vehicle Spawn Blocking + Round Start Chopper RPG

One thing us flyers love, is when we spawn into a fresh conquest and we get the helicopter spawn, it's ours, you can almost taste it, then you run to it just for your teammates rocket to fly by your head and blow it up. Then you're stuck there walking to an objective after like a bum cause you went for the chopper, not a tank or a jeep, but the now exploded remnants of the chopper.

So ok, that's not so bad honestly, I'll just wait until the chopper spawns.

Oh wait... The guy who blew up the chopper is now standing on the spawn point preventing it from spawning.

No problem I'll just drive a jeep and ram him off the cliff so that we can have a chance to get the chopper.

Oh wait... The guy who was spawn blocking before has a teammate who's now spawn blocking with one of our teams tanks.

Now there's 6 people sitting in the spawn with all the teams vehicles blocking the chopper spawn.

If you're a chopper pilot, or a gunner, you've definitely witnessed this, started this, or were a part of this. 
With all of the additional stress of enjoying piloting in battlefield, like the Laser Designator insta-kill bug, (I think it's a bug at least) getting spawn locked by enemy team so you can hardly fly at all during the match, or just simply crashing into the floor... It's stressful enough that this is what you have to put up with before you end up in one of the other situations mentioned above.

This is so dumb lol, surely there's a solution we can come up with to resolve this. 

My suggestions:

Spawn protect the choppers for like 10 seconds on round-start so that someone can get in and trigger the friendly fire protection.

Create a small 1 second delay for interacting the chopper after it spawns. Give the people in the spawn menu the advantage and this will effectively discourage blocking the spawn of the chopper and prevent this insane spawn camping/football pile in the HQ.
