how can you drive two vehicle attached with chain ?

so i just figured out how to attach a chain in to two vehicle now i have some issues on how can we control both vehicle for example i want to drive it to a bollard
sometimes when i drive both vehicle attached with chain the two vehicle will drive straight but at some point it looks like they try to avoid each other and driving in seperate ways
so i want to make the car drive through the bollard, here i will give you the example videos

so please if there's anyone who can teach me or give me a tutorial to make a scenario like the videos shown i would really thankfull

 

Godzilla had a stroke trying to read this and died.

That is one hefty mp4

 

I'm curious too

 

How to control several vehicles/props at a time:
1. Pause physics
2. Go to one of the vehicles
3. Press gas pedal
4. While you're pressing the gas pedal, go to the other vehicle
5. Now raise your hand from the gas pedal
6. Press gas pedal again
7. Start physics again.

By doing that, the first vehicle will press gas pedal automatically for ever until you press the gas pedal on that again

Hope this helps

Also you can do this for the bollards to raise them all at a time:
--first bollard
1. Go to the first bollard
2. Press PageUp
3. While pressing PageUp go to the second bollard
--second bollard
4. Now raise your hand from the PageUp key
5. Press PageUp again
6. While pressing PageUp go to the third bollard
--third bollard
7. Now raise your hand from the PageUp key
8. Press PageUp again
9. While pressing PageUp go to the forth bollard
--forth, fifth, sixth, ... bollards
Do 1st and 2nd and 3rd steps like the other bollards

 

Bruh, did you even try this?

 

Yes and it works for me. Maybe you couldn't do it correctly

 

He was using his brain, unlike some people. If you actually knew what he was talking about, you wouldn't be making comments like this. He knows what he's doing and it makes perfect sense.
He's using common knowledge (eg. holding down the gas pedal while switching cars makes the function permanent) and applying it to the needs of the person, who started this thread.

 

Yeah, it seemed a bit difficult to me but when i tried this, it was really useful
