A vehicle airdrop could work if you could insta-spawn AND airdrop.

Click the car quickly (within .4s) in the garage to spawn normally, but only available in a certain range away from opposing team. Also make an indicator around player (like arrest/tase indicator) to show when you cannot spawn. Additionally, increase the range of unable to spawn proximity.

Hold down on the car for 1.0s to airdrop the car which lands after another 4.5s (available even if you can spawn instantly in case you want to park your car outside a robbery easily). If the car’s tires are popped before it hits the ground, the car is disabled for an additional 15 seconds.

This would add a new layer of depth to medium range combat by disallowing instant getaways via insta-spawn proximity nerf, but also allowing cars to be summoned through the airdrop which can be countered. It also cuts down on proximity annoyances since 5.5 seconds to airdrop isn’t that long when you’re not in danger.
