Agree with the majority, there's no need to ban them, least of all "standard car types".
The Snooper or other dedicated caravan/lorry sat-navs are no different to "standard car types" with specific POI's loaded. (Caravan Sites, Low Bridges, etc.) except that they have a rather over inflated price.
As with ANY sat-nav, you still need an element of common sense when using them AND you need to ensure you have them at the correct settings. For example, set to "quickest" and you're likely to be taking more detours and back roads than you'd like. Set to "fastest" and you're more likely to stick to the main roads. But they are not infallible. If I see what looks like a detour down a potential narrow road, I ignore the sat-nav and carry on, allowing the sat-nav to re navigate and recalculate. And as others have said, I always check the final approach roads as listed by the CC (or similar) or by using a map (even AutoRoute or Google Earth).
What's the difference between "quickest" and "fastest" - do you mean "shortest" vs "fastest/quickest" ?
My main comment wasn't about being directed onto back roads (all route planners will do that if "shortest" is selected) but being directed to use 30 miles of motorway/dual carriageway rather than 16 miles of single carriageway, but still "Primary" road status.
The entry level Snooper satnav isn't expensive - it's free if you pay a once-only £95 for life updates, daily updates for the camera database and annual updates for the mapping.
