The 3rd device is your BRAIN.
Last year I put my Supe into an armco barrier while doing less than 20 mph on a roundabout. It was about 6pm on a Sunday night, very slippery. It was starting to snow even. The roundabout is like dish tilted with me heading from the top towards the bottom. The combination of greasy road surface and the adverse road camber pushed the back end out left. Only doing 20 so dead easy to control – NOT!!! She then fishtailed right then left and by the time I was heading towards the Armco, I must have been doing 5 mph. ABS is kicking in too late. All I can hear is the sound of glass and reg plate breaking and plastic creaking from the front. SOB! It was like one of those slow motion crash test dummy films. The damage looked a lot worse than it really was and even the HID bulbs were intact. I was mega worried the insurance would write her off but the assessor decided to fix her.
Silver lining was I got two new headlights worth £300 each, complete new front end with drop-down spoiler and front respray for a £250 excess. Result! But I wouldn’t recommend this to anybody sorting out heavily chipped paintwork. I could’ve let her spin out but if I went off to the left I would have rolled down a 15 feet bank. Ouch! Since then TC never gets switched off. And the nightmares continue. Today you can see the storm blue paint on the bent-up barrier and all my mates call it Chewie's roundabout. You can't miss it if you're driving past GCHQ in Cheltenham.
