"Enemy of my enemy is my enemy's enemy"(*)
On the road, EVERY other object is a threat - it's just that some have a greater threat value than others.
"Threats" in an Urban travel enviroment would include stupid 13-yr-old mom about to push Baby Chav's stroller into the road, Lycra-clad Cycling Tart trying to hit the speed of sound in the town center, Doddery Old Couple off to collect their pension (oops, not any more! - didn't the UK equivalent of the IRS insist it all go through the banks to prevent 'money laundering'? Or was that just to make it easier for the gubmint to cream more off the top?), iPod-wearing teen crossing the road without thinking about the gasoline-powered death machines hurtling by inches off her shoulder and petrolhead trying to launch his rocket-powered rollerskate off the nearest road hump.
"Threats" in a non-Urban travel environment include Doddery Old Couple in Decrepit Old Volvo doing just over half the speed limit in the middle lane, Company Rep in his German Bulgemobile trying to shout into his phone over the sound of his electric razor while steering with his knees and balancing his Starbucks on top of his satnav, manic trucker short on sleep and close to delivery time, six-legged demi-centaurs in designer jeans, mass-produced 'imitation real fake leather' dude boots and silly hats hiding behind hedges waiting for the only car currently moving in three counties to come along before they start to trot down the middle of the blacktop (despite the nice wide grass strip not 5 foot away), baccy-chewin' Good Ol' Boys who own the road just 'cos they've "been drivin' since before that gol-durned peanut farmer got in the big house (sonny)", and The Man doing 53 on the freeway and watching everyone's front ends dip like crazy as they realise they've got a county mounty on their front porch...
Presumably the Taurus will have some sort of threat assessment routine built in so it can discriminate between some poor sap keeping to his own lane or the occasional pede who remembers that ROADS are for CARS, SIDEWALKS are for PEOPLE, and anything that looks like it might be heading for an attempted co-location in the physical space-time continuum...
I believe Volvo UK are currently running an ad where some great big frack-off 4x4 narrowly misses colliding with a stationary car because some eejit elephant just happens to squirt water all over the windshield as the tank, sorry *car* is approaching a traffic queue at a stop signal, and all due to it's wonderful inbuilt safety features... wonder what that particular safety feature might be... like a short-range RADAR with command authority over the DECU and ABS, perhaps?. (Digital Engine Control Unit, Automatic Braking System). Not sure why they only seem to fit it to the top of the range road-going tank though, surely if they are really *that* concerned about *all* their customers it should be standard fit on all vehicles at no extra cost, nyet?
