There isn't any other immediate technique available... changing of the roads and motoring habits will take time.

But the "road the way it is today" did not spring up overnight... so why should we insist on using a technique that may not apply to "road the way it is today?" This is akin to standing in front of tanks with bows and arrows and saying... "well we have no other way... "

We can change laws, we can insist on changes to roadways... but to do so we must first acknowledge that there is a problem... and not just "go along."

Bear in mind that "the road the way it is today" is not the same road of yesteryear... it is more crowded, faster, and the motorists are more distracted... still want to use the same old techniques?"
