i agree the system could work well and there are systems like this that gather info from users out and about

ie sat nav systems using a system like this to gather information about traffic jams and clear roads etc

i have to agree with cjp though i dont think speed bump info is needed maybe speed cams and conjested roads but there allready apps collecting this data or websites that are collecting this data

keep the idears flowing though mate like i say its great to see users coming out with idears like this

iam not knocking your idear and as a user i appreciate idears like this
