Just retuned home from a couple of hours work. (at my real job) Leaving home, on the outskirts of Cambridge, its a 50 zone. Drive for 700m and it changes to 60. Another 50m and it is 70. This is the rural area north of Cambridge. Drive for 2 klms and it changes to 80. On the same road it goes back to 70. Drive for 1 klm and its 100. There have been no changes to the road conditions, surface or whatever.
In 4 klms I have gone through six different speed zones. I have been travelling this same route for 2 years and have never seen an accident or any evidence of any accident.
Can someone explain why these changes have suddenly occured?
