The problem occured when I was on a 10 mile stretch of 50 mph avg spd chk roadworks on the M25! Maybe I need to put my foot down occasionally! I was wondering if there is any way...

I wonder how much energy and materials are needed, and how much pollution and waste products are generated in making all these parts, which fail and need replacing... Welshtom's got me going now!
