The correlation between fatality rate and speed of impact is so well established that you should just be doing your own research here and looking it up. If you can't be bothered, the answer is that it depends on which 5 mph it is. Speeding by 5 mph in the 30 mph school zone mentioned above is substantially increasing risk of fatality of pedestrian hit. Likewise, the correlation between speed and time to stop is also rather well established.

I wasn't asking for the increased risk of fatality assuming there was a crash. We are talking about the overall impact of the decision to speed, so we can't assume a specific scenario. Of course which 5 mph it is also matters, as you've stated. It also matters if it is 2 mph or 10 mph. I still think GP's assertion is ridiculous. Minor speeding, which is what most people do, is not "close to murder" by any reasonable analysis.

  There have been quite a few improvements in car technology since it was released, but the first Google result I could find says that 1 mph increase in average speed results in a 5% increase in injury accidents: http://www.trl.co.uk/online_store/reports_publications/trl_reports/cat_traffic_and_transport_planning/report_the_effects_of_drivers_speed_on_the_frequency_of_road_accidents.htm http://www.trl.co.uk/online_store/reports_publications/trl_r...

  Perhaps not, but that's not what I said, either. I said that on the dimension of likelihood of causing death, speeding is closer to murder than theft is. Let me offer a thought experiment: You're a parent in a nice quiet neighborhood. Scenario One: You come home from work and your front door has been kicked in. Someone stole your laptop. Scenario Two: The neighborhood kids are playing ball in your yard. A car drives down your street at 90 mph. Which scenario makes you more angry? When someone steals my stuff, I get sad. When someone ignores a stop sign while I'm in the crosswalk, I get angry.
