How many laws did the 'law abiding' motorist break?

At least one.
Possibly more, for example--

Speeding, parking the wrong way at night, on yellow lines, on zig zags, outside schools, pavement parking, obstructing traffic by inconsiderate parking, driving while drunk, on mobile phones, with no car tax, no licence, no insurance, no MOT, illegal plates, overtaking on double lines, due care, bald tyres, faulty brakes, one eyed monsters, no rear lights, no brake lights, no indicators, fog light abuse, faulty steering, windscreen obscuration, darkly tinted windows, child seat abuse, no seatbelts, insecure load, one way street abuse, amber/red light jumping, cycle box abuse, bus lane abuse, box junction abuse, death by dangerous driving, excess smoke and noise from exhaust, duff suspension, leaking oil, cash for crash fiddles, underage child in front, lights causing glare, over weight limit, ignoring no entry signs, parking without permit, not having control of your vehicle, improper use of horn, using horn at night, no in date photo licence, no licence application after long ban, without prescribed eyewear, failing to stop for police/lollipop/zebra etc - ran out of space

You miss the point.
If a motorist accelerates from rest to 90mph and continues at 90mph on a 70mph dual carriageway for 50 miles then decelerates to rest, how many speeding offences did the motorist commit?
Lets say she was caught by 3 speed cameras along the route.
Did she commit 3 offences or only one, the one where she went from below to above the speed limit?
