Vehicle spawn camping

I’m pretty surprised 343 hasn’t addressed this but why can’t they put a 10 second grace period where your vehicle cannot be hijacked? Especially in maps like arc where it is very easy to hijack since the bases are so close together. I understand that it’s a lot smarter to spawn vehicles in home base but why should we have to do that when a fix could be so easily done? This should be a ten second grace period for hijacking only, not invincibility to be absolutely clear.
