Comepletely agree
Several years ago, we had to call an emergency ambulance out for my Dad. The emergency services had the full address but couldn't find the house. Why? Because the road name reported by the satnav (a major road on the outskirts of Sheffield) was incorrect. I ended up waving at the ambulance as it went past trying to attract the drivers attention. The ambulance crew weren't local which didn't help matters. I've just checked on Google maps and Multimap / Live and they both show it incorrectly as well. There's obviously no hope...
