Safety Drive Following Distance

Recently there has been a big push in my group for what my company calls 'Safety Drive.' There are seven key points for Safety Drive which are posted in at least size 144 font on the wall over the department recycling bins. I cant remember all the factors, but they include looking back for bikers when making a right hand turn (think left hand turn if you are driving in the US), having clear windows and looking out them before you start driving.

In driver's training I remember learning about the two second rule of safe following distance. It turns out that in Japan there is a different rule for following distance. Signs are randomly posted on the highways at intervals from 0 to 60m, you are supposed to check for a safe following space by distance rather than time. I guess the Japanese rule assumes that everyone is driving the speed limit or can calculate in their head the effect that an increased speed has on how much distance is needed to stop.
