Emergency Vehicle Parade

I think it would be awesome to be able to generate and direct the route of a emergency vehicle parade. Have the streets of the guided route auto blocked through code or having physical cops and barriers along with a blocking code running would be awesome as well. I think in order to do those it would be a big help to use traffic policer by @albo1125  as the game format along with road signs and etc.  and then using Traffic Control by  @Stealth22 would be able to block the predetermined route of the parade. That would leave the coding of having the police vehicles and other emergency vehicles following the directed route in a steady formation. Also Stopping all call outs for the duration of the parade and pedestrians from wondering in the road but it would be cool to have them off to the  side behind police barriers. And then allowing the user to choose to take part in the parade driving a vehicle if so allowing the driver to select his place in the back front or middle of the parade. Or as a road officer directing or observing the parade. Now what this could potentially brings is allowing us to honor our men and women of emergency services especially with what's been going on now and days... This Could ALSO ALLOW priority escorts whether it be for a celeb or gov official or may be even a funeral service escort. I think it would be a really cool thing to add. I don't think anything like what I described exists but if it does please let me know thanks!
