Re: Wrong question
Absolutely. They're also missing the fact that driving is a rules based system and we've all had the rules drilled into us. It's a moving puzzle we're adept at. Psychologically we should be able to incorporate the two much as we do with a satnav;- we can glance at it, instantly read what the symbols mean and incorporate that into the road ahead and our driving strategy. Satnavs haven't caused a huge spike in accidents have they?
All this research has proved is people facing a test they're unfamiliar with in a pressure environment are distracted when the already unfamiliar puzzle changes. As Ledswinger so eloquently said;- "What a load of old cock" ""Boffins" my arse."
