I disagree. If you want to get somewhere quicker, set off earlier. The speed limit is a maximum, not a minimum and I rarely if ever go over 50-55 mph. The other lanes are for overtaking only, not sitting at 80-90mph plus. The only time I'm ever in those lanes for any length of time is if I think the traffic is deliberately and persistently exceeding the speed limit and I pop into the middle / outside lane with the cruise control on 70 for ten mins or so. Of course you get the odd dickhead flashing and tooting, but overall I think I've prevented many accidents over the years.
