I was reading this twitter post and it made me wonder if you have any ideas to stop speeding by car drivers? Have any of these ideas been tried anywhere? I'm also interested in unintended consequences.

fact of the day: Sweden once experimented with a “speed camera lottery”. Those who drove within the speed limit were automatically entered into a drawing where the prize fund came from fines that speeders paid.

They tested it in a few different cities and I haven’t read the results of each one, but in Stockholm the average speed on the selected road decreased by 22 percent.

Kitchen knives are frequently used to stab people. This results in serious injury or often death. Most stabbing murders are perpetrated with kitchen knives, reflecting the huge numbers of knives available (most homes have one), and where most murders happen (in the home). (I'm talking about UK here).

Kitchen knives have a cutting edge and usually a sharp piercing point. There's nothing that can be done to make the cutting edge safer. But we can look at the pointy tip.

Pointy tips are useful, but we tend to find that only professional chefs or experienced home cooks use them. Most people cooking at home don't use or need such a pointy tip.

There are some companies releasing knives without the pointy tip, and I'm interested to know what you think.
