Just remembered.......
Whilst stopped at lights in a downpour with just my tonneau cover on I put up an umbrella.
Worked ok til I had to move on and attracted some odd looks and photos... was in the middle of Mumbles on a busy day.
Also used one leaving Malvern at some temp lights - was a passenger with Aerotaff driving my car for a try out. umbrella
