This device would gain us 1-2 more cars per parallel parked city block (if it took off). You simply can't get out of a parallel parked space without extra room due to steering angle.
I find it is mostly about whether I have the patience to find the perfect position/angle of approach, timing of turn etc. Much easier to simply drive along and find a slightly bigger park.
Combine this with auto-park though. Could be nice.
