That was civilised.
Your rant at the top of the page however wasn't and bordered on the edge of rudeness. De facto you probably insulted a few of us around here. I have had a Merc SUV and a Cayenne and other SUVs in my time, though at the moment I run around here in a A3. They were aprops for the environment I was in and gas-guzzlers - well I would challenge that as my Porsche (the Cayenne Turbo) ran at about what my A3T does....also I rather like cars and was involved on the fringes of Formula 1 for a while...... And just because some of us have decent jobs, command good salaries doesn't mean that we are out of touch with reality. Indeed, I would argue we actually have a better appreciation of society in being able to see it from many levels.
There are many bad practices on the roads - people coming right up your rear end (if they were to be hit from behind?), jumping lights, hogging the middle lane or overtaking lane of the motorway, parking in disabled spots - I can go on virtually endlessly.
Seriously, chill out on this - there are more important things in life, certainly for me, and I am sure this is true for you.
And lastly, fear not, most of us do not know the Highway Code to the n'th degree - even the boys in blue can be caught out....
