I could be wrong, but I think you're misunderstanding incision's comment. The way I'm reading it, he's not arguing with the fact that having a jammer operating in the guy's is pretty idiotic. What I think he's saying is that he's got sympathy for what drove the guy to go to these idiotic lengths - the fact that a large number of drivers give pretty much no thought to safety by using their phones when they drive. On my daily 5 minute walk from the bus to work, I will typically see upwards of a dozen drivers staring at their phones, presumably either reading or writing a message, whilst they are moving - ranging from people inching along in slow moving traffic in places that pedestrians could easily (and legally) be crossing, to ones doing 30mph+ in free flowing traffic or even pulling away from the lights based presumably on nothing more than seeing out of the corner of their eye that the car in front has started moving. I've fairly regularly seen cars meandering quite a long way through red lights simply because the driver was clearly paying no attention to what was happening on the road in front of them.
