I think what is happening here is that the towtruck (maybe a few other vehicles too) has/have some sort of hidden flag added to it/them to stop the peds getting out of the way of it when their siren is on. If you set up a siren on just about any other vehicle, you will get the same thing, traffic will move out of the way as you get closer to it, but if you use your ford flatbed to replace the towtruck it will work just how you want & peds will ignore you etc.
Rockstar use hidden & uneditable advanced flags to make edits to certain vehicles (the 'fbi' is the only vehicle I've found that can carry 4x dispatch peds for example). The flags are tied to the vehicle name, so the only way to use the characteristics of those flags is to replace the vehicle that has that flag.
So, in this case, I think you are going to have to either:
- Use your Ford flatbed model to replace the towtruck (or perhaps towtruck2, if it has the same characteristics),
- Find another vehicle that has the same flag applied to it & use that instead of the flatbed.
The 2nd option is probably best, you can likely find an airport vehicle or construction vehicle that you don't care about & replace it with your ford flatbed model to get the results you want.
Basically, take a little drive along the motorway in all the flashing lights vehicles you can find in the game & see if any of them have the characteristics you want & don't force peds to pullover etc.
If you find one, replace it's model with your Ford flatbed model & see if it has suddenly gained the 'no peds pull over' characteristic
yea that makes sence, i might have to try that, I dont want to replace the towtruck one (i have a towtruck mod that i use to go tow cars that need help, so i would like to still use the towtruck as that mod uses the towtruck model and nothing else), but i might try the towtruck 2 lines as that one doesnt get used by any mod i have , and i think stop the ped you can change what towtruck model comes when you call for a flatbed, i guess that will be the better option, thank you
Towtruck2 slot works perfectly, if any mod wants to , they can close this and mark the guy above me as the anwser
here are 2 videos showing it in action
