I think you're probably right, and it seems perverse to me to encourage or pander to a failing that's already too prevalent. It's a vicious circle and I don't see where it ends. There seems to be a horrible democracy-in-action thing going on where, because enough people would apparently like to be able to use their cars to get about without having to be engaged in the driving task, the authorities are, with a staggering lack of responsibility, actually trying to make that wish viable.
Bowling ball driving worries me a lot and I find the idea of turning 30 mph bowling balls into 20 mph bowling balls of little comfort. In the sort of busy, heavily built up areas where driving at 30 is likely to be inappropriately fast, the last thing you want to do with someone who'd rather be thinking about other things while driving is to encourage them to believe that adhering to a lower limit is anything close to sufficient, because that sort of driving environment is just too complex for speed fixation to cut it. Whether they want to be engaged or not, the message that needs ramming home is that they have to be - that if they don't want to take it seriously they're not suited to the responsibility of piloting a tonne-plus of death machine down a street full of squishy innocents.
The more that the environment presents drivers with opportunities to hurt people, the more that focussing on what the speed limit should be misses the point, because adherence to the limit is such a minor adjunct to what actually matters.
