Thinking about this on the train this morning I reckon you could get close by using Doppler sensing sonar along a corridor with one way doors at each end. A Doppler shift which indicates somebody going the wrong way would disable both doors until humans sort it out. It could probably be augmented with a camera based system. There would inevitably be false positives from kids darting around, etc but you wouldn't have to shut down the terminal.

(we assume most people aren't complete morons in Australia).

Did you _see_ the results of the last election?

Touche.

But in our defence, only 32% of people voted for the Libs, the remaining 13% was made up of the various national parties. The 5% that got them over the post were due to dodgy preference deals.

But realistically the dregs of Labor weren't getting back in to office.

I found a nokia at a tram stop once. It was just the internal structure and battery, but a bit of hunting around in the gutter revealed the case. It had been dropped on the road and repeatedly run over. I snapped the lot together and found the most frequently dialed numbers (parents in Malaysia, not calling there to say I had found their daughters phone smashed on a road in Melbourne). Called her boyfriend and he arranged for me to drop off the phone. Very strong bits of gear, Nokias.

Consider this scenario. I am merging right to make a right turn.

  1. Indicate right
  2. Wait for a car to give way
  3. Merge one lane to the right

This doesn't work with automatic cars because they don't understand hand signals. Instead I just have to merge and hope the overtaking cars are going to give way. If this behaviour becomes common, people will start merging without indicating in the expectation that automatic systems will take care of the resulting conflict.
