there is 1.5 minutes worth of clips from that 1.5 hours we have condensed that down to. for that person, rather than spending 1.5 hours at the roadside, if they watched 1.5 hours of condensed clips from a sensor, they will get a much better understanding of what is the problem at this particular location. peter also told me that councils will probably take a while to know how to process this data and execute plans based on it. but it is not the only stumbling block. 0n the project we have been collaborating with ford, we actually found it quite difficult to get people to agree to put a pid in their car, even if we paid them. if we turned around and offered somebody money they were still turning around saying "ooh, no, i don't want that". as i mentioned before, i was so aware of being tracked, my driving being measured, so it doesn't surprise me that they struggled to get volunteers, managing only 200 and the whole country. but with more modern cars having modems anyway to connect to the internet, is being tracked something i actually had to worry about?
