I have a Honda Accord, and intially had some problems sitting correctly. I did not leak per say, but felt uncomfortable. On longer trips, I learned to sit to one side so the AUS is not felt or to cause me to leak.
Most new cars and office chairs have this molded foam seat. I think that is the problem because it acts like a softer version of a wood seat. I am now sitting on a molded foam office chair, just like the Honda and I am aware of the pressure on the cuff.
I have the same issue with my wifes Mitsibishi Outlander...
By the way, how do you like the AMS 800. By your lead in comment, all is good!!
Personally, it has changed my life.. I would hate for anything to go wrong. I blogged with a guy on my Bladder Cancer blog site where after 3 years his developed a leak and no longer works.. They will have to go in and find the problem.. Always a possibility.. Hope not mine (or yours!!).
