Unable to switch to traffic vehicles

After spawning traffic vehicles I usually switch to those vehicles to change cars if I don't like them (or if there are multiple big vehicles like busses or trucks) but I am unable to do that now. (I checked if the key that is supposed to do that works)

 

It seems like they removed the ability to do that. You can spawn the cars you want to see in traffic and press the "start traffic" button though. Unfortunately this doesn't work with vehicle pooling

 

that's annoying (and laggy probably)

 

In the options menu under the gameplay section, So >options >gameplay >traffic there is a checkbox named "Disable switching to traffic vehicles" you most likely have that box checked. If you check that box and turn it off you can tab to traffic vehicles

You also have to remove traffic and respawn it for the option to take effect otherwise checking that while they are already spawned doesn't seem to work.

The ability to tab through vehicles is still a thing its just an optional checkbox now
