I downloaded Blender and the files above.
Unzipped City Segment 1, imported - It was exciting to see a curvy line. I thought maybe I was onto something. I could highlight and make it yellow, zoom in and out, move the line around, but it didn't seem to match the map birdseye picture? Weird. Later on I went to import again but nothing appears on the page? I'm at a loss why something appeared then later on, nothing..?
Don't worry viewers - I'm not going to drag this excellent NFS discussion down to rock bottom when we're lucky to Pros like A3DR and others about.
I love the image with the ZR1 at Alpine. I'm glad it worked for you
