I’m not sure if its available, maybe on ultra luxury cars but there should be a system tied in with emergency vehicles and even railroad crossings that will give the driver a heads up warning. These new vehicles, some with noise canceling like my 2012 Equinox are too well sound insulated. Especially on the highway and all of a sudden i “might” see the warning lights in my rear view mirror, i never hear them until they are right next to you. Just a big flashing red icon on the GPS screen would help for some.
And that darn urea additive thing for diesels! Has kept me from buying ANY new diesel from pickups to semi rigs. Get rid of it!
Go to your local diesel performance shop and disable the urea.
True story...
I was on a trip in a diesel pickup (brand new 2014 F250) with a trailer to a trade show in Texas from Washington. In heavy traffic, through Las Vegas the damned thing, had the governor kicked on and the truck wouldn’t go above 20mph... In heavy traffic. None of us in the truck knew anything about this urea crap. We manage to pull off somewhere and call a guy at the gas station told us about exhaust fluid. That’s crazy. Who ever heard of such a thing? Do we find ‘exhaust fluid’ next to the shore-line, prop wash, left handed screw drivers? Sure enough, there was an extremely expensive quart size bottles we had to buy and fill up exhaust fluid.
