Adaptive Cruise Control - It Takes a Long Time, Right?

I think it's really interesting to think about, you know, is right in that like 2007 ish range where Tesla started. And a few years later you have Uber with ride share, and right in that mix was local motors revolutionizing manufacturing. But when you look back at the technology that led to adaptive cruise control, that was being developed way back in the 70s and 80s in terms of the auto industry obviously radars were developed from a military perspective long ago. It took 20 plus 30 plus years to become standard technology in automobile.
