I'll try to keep it short - I'm sick of fighting over an objective (or sometimes even not!) and then encountering a tank or APC that I could not hear coming until it's in my face.
It's infuriating as much as it is silly. It's absurd that we are playing a game where firing without a suppressor auto spots you on the minimap 150 m away (as well as 3D spotting yourself at a lesser range if not using a flash hider), yet vehicle audio only becomes meaningful within about 30 metres.
I just want to be able to hear them coming. I don't think I'm alone on this but wanted to share.

You're not alone. This issue is known since the beginning and nothing is done.

Check your settings, I can hear all cars a mile away.
