In heavy rain last night, the bike ahead of us with no lights decided to merge into the blind-spot of another car also merging into the central lane. He lived through no good management of his own.
This bicyclist with no lights then joined a pack of three others to slow the traffic down behind them. Only one of the four bicyclists had any lighting or reflective material at all.
They moved in a pack, so the cars including ours could not get around them because the traffic was heavy. Fortunately, the street was well lit so you could see them, just. Bikes must go.
The average commute by public transport is 40 minutes as compared to less than 25 in a car. 74% of Aucklanders drive to work and another 9% are a passenger in a car.
No information was available on those who bike to work because only 1% of Aucklanders bike to work. Only 2% of all New Zealanders take a bike to work. The sample size was therefore too small. Yet another reason to ban bikes at night. Few commute on this mode of transport in Auckland.
The near identical commuting distances irrespective of the mode of transport except walking is further evidence that people are quite discerning in balancing commuting times and job selection as per the theory of compensating differentials. Indeed, average commuting times in Auckland are much the same as the average commuting time in America.
Improving the commuting times in one mode of transport will mean people simply take the mode of peak hour transport that is suddenly become less congested while others who were not going to commute at peak times or start commuting at peak times as Anthony Downs explains:
If that expressway’s capacity were doubled overnight, the next day’s traffic would flow rapidly because the same number of drivers would have twice as much road space.
But soon word would spread that this particular highway was no longer congested. Drivers who had once used that road before and after the peak hour to avoid congestion would shift back into the peak period. Other drivers who had been using alternative routes would shift onto this more convenient expressway. Even some commuters who had been using the subway or trains would start driving on this road during peak periods.
Within a short time, this triple convergence onto the expanded road during peak hours would make the road as congested as it was before its expansion.

“We do not believe any group of men adequate enough or wise enough to operate without scrutiny or without criticism. We know that the only way to avoid error is to detect it, that the only way to detect it is to be free to inquire. We know that in secrecy error undetected will flourish and subvert”. - J Robert Oppenheimer.
