I reverse my Civic in and when the sensor note is continuous I know the front is in far enough for the sectional door to come down. My wife parks her 206 next to me, but drives in.
This means she either drives too close to my workbench and I can't get to my reserve wine rack which is behind my Civic, or she parks with the back too far out, and the door will hit it.
The pavia blocks seem to work Ok.
