I guess they have enough money from gouging people that "speed" (and I am here defining speeding as breaking an artificially low speed limit, not as doing a speed that is not reasonable and prudent). The ticket is the last thing you worry about--you get gouged for $800 and up during the 3-year period it remains on your record per speeding ticket. The insurance companies fight to keep speed limits artificially low (and frequently have traps--you are doing 45 on a 45 MPH zone with a 45 sign, where there is a 35 sign inconspicuously posted a few meters beyond the 45 sign. Invariably there will be a cop waiting to write a ticket. A few meters later, it goes back to 45--the drop is without good reason.
If they would have sensible (or no) speed limits, this scam would be cut off. The insurance companies would lose their $800 per speeding ticket if the speed limits were posted at 85 or 90 instead of 55 or 60 (when it is safe to actually do 85 or 90), or posted 55 instead of 35 or 40 in suburban feeder highways where it is safe to do 60. And, if they would remove the truly dangerous drivers (the aggressive driver, those whose passing skills leave a lot to be desired, and the obviously drunk drivers), we could have even fewer accidents.
Fewer accidents, plus deregulation of insurance, leads to lower insurance premiums. Competition drives down costs, while the bad insurers (those that deny every claim or find flimsy excuses to jack up premiums or cancel their policies) get bad Internet publicity. By the time this settles, that Progressive insurance woman that always seems to live for insurance will have to find another job. And, we can actually have ads on TV for products that people actually like to use--like that amusement park trip.
DOWN WITH UNREASONABLY LOW SPEED LIMITS!
