Motorways

Over the last few weeks I have done a fair bit of motorway driving, trouble is it's a pain in the arse.
First off the motorway network in Wales has a terrible Mobile phone coverage, this means staying in touch is at best a struggle, at worst dangerous if you need the emergency services in a hurry.
Second off fuel is not only hard to come by but dammed expensive... not however as expensive as the food at the services! That's ridiculous! £3.90 for a sandwich and £2.20 for a cup of tea, I mean whats it made of? rare exotic herb, an orchid perhaps? no just a normal bloody ham sandwich. The words RIP OFF come to mind.
Another thing why have huge illuminated signs saying pull over if your tired when there's nowhere to go? The services are about 30-40 miles apart so thats around a half hours driving to the next one if your lucky, and you dare not just come off at any old junction, many of these lead stright onto another motorway, so now your not only tired but going the wrong way as well. Maybe some pull off rest areas might be sensible, but I suspect too much to hope for.
