I drove a 99 corolla until recently... After I got hit this January by a stoner, I got a 2013 corolla... The enhancements are awesome: I can no longer see cars in my blindspot by simply turning my head - they moved the side support forward by about an inch and a half... The mirrors are an annoying cut-off shape that means I can no longer see the car 2 lanes over in the lower corner of my mirror... For no apparent reason, they raised the plastic in front of the wind screen so I can no longer comfortably see the front of my vehicle when parking... They also raised the trunk lid to the point that the windscreen is substantially smaller and I have poor rear visibility... And my favorite, they moved the cup holders behind the gear shift rather than keeping it in front, so I can't properly shift anymore if I have anything larger than a can in my car... so I can either drive de-hydrated or keep the drink between my legs, both sounds really safe. Oh, and my favorite, they also put a lid on top of the center console storage space just in the right place that I hit my funny bone when shifting into 4th gear.
So explain to me, why do I need to have a wireless car-to-car system if the manufacturer of the vehicle seems hell bent on making the vehicle as hard to drive as possible (they call it modern styling)? It adds to the cost of the car, increases the weight (my car, despite 8 more horses, is almost a second slower 0-60) and the end effect is questionable. There are so many cheaper and better ways to make cars safer...
