I don't mind if it doesn't give me the optimal route coz I can review what it';s doing and ignore where and when I please (unlike when "self drive cars" com along). What pees me off is when you put in a post code and it doesn'tjust go there, it asks for a house number!
Say you want to meet someone at The FIve Bells in Stanbridge. You've never been there, but you have the post code, which is LU7 9JF - so you say find me post code LU7 9JF and it says yep, got that, give me a house number. What? If you don't give it one, it gives up altogether. You cant put "the five bells". So you put "1" and... gosh, a UK post code is such a small area that there isn't a number 1 in the area in question. So you have to keep guessing. IN this case, "9" did it. But in a town the street might run up to 800 houses, and will probably have 25 post codes. You'll be there all day guessing a house number if all you have is a house name or a business name. If I put in a post code, I want to be able to skip the house number and just go to the area of the post code. My problem if that's not close enough! If I put in a town name, I don't want to have to give it a street, just take me to the town centre or better yet, the nearest edge of town, like my last car's NavTEQ unit would.
