When I learnt to drive lorries it took me a while to get used to the slowness and also the space needed by an artic. Lucky that was while I was learning back in 1996 on the old Wembley stadium car park!!!! Thank you Wallis School of Transport
Since then whenever I've given a lift to friends in the cab of rigids, but esp in artics, they've always expressed amazement as to how different the road looks, how you can't try to outrun traffic lights changing to red and how cutting-in in front of a lorry can halve its stopping distance.....
I've always thought that an hour or two as a passenger in the cab of a lorry would benefit every car driver and should be a compulsory part of the driving test.
As for driving after being on a boat for a few weeks I always try to ease myself back into what seems a hectic and dangerous way to travel!!
