An item from the AP notes:

MADISON, Wis. - The Wisconsin Supreme Court says police were within their rights to pull over a drunken driver whose vehicle briefly crossed the center line.

The unanimous Supreme Court overturned that decision Wednesday. Justice Annette Ziegler says the stop was reasonable because Popke was driving erratically at 1:30 a.m.

Does this mean that police do not have probable cause to pull over a driver driving erratically at, say, 1:30 p.m.? What if the police had phoned in the tags, and noted he was a repeat drunk-driving offender — does that represent probable cause, or is that viewed as some kind of “profiling” (e.g., profiling hazardous drivers)?

There’s a curious discussion over on the bulletin boards of the Smart car owners site, oriented around the question of whether the drivers of other cars consider it an insult to be passed by a Smart car. Apparently the phrase “passed by a Smart” is highly Google-able.

Most theories seem to revolve around other drivers not considering the Smart a “real car” — i.e., they take umbrage when the smaller vehicle passes them (masculinity issues or some such), or the site of the small car hurtling along at an “impossible” speed makes them think they themselves must be driving slowly.

When I drove the smart in NYC, I found two general reactions: Versions of the above, and then outright, gushing approval (typically from pedestrians, though, more from other drivers). Sometimes people would seem to be upset that I had passed them, as they would then rev their engine to pass. As a side note, I occasionally witness this on a bike as well — drivers desperate to get ahead of me, even as we approach a red light (but a bike will always win because a car has to begin braking sooner, and because a bike can ride in the space in-between of course), almost as if they were trying to valiantly justify their automotive choice, or reclaim its presumed velocity advantage.

Via Strange Maps (via Kottke), an interesting project from Rice University measuring the size of ring roads globally…

In London Orbital, writer, walker and Londoner Iain Sinclair approaches his favourite subject – his home town – by circumambulating it. The book details his trek along the M25, London’s ring road.

While the identity of the actual highway(s) surrounding Houston and depicted here remains elusive, it is beyond doubt that the Texan city has a large surface, a fact attested by a map posted earlier on this blog (#327), the discussion of which also touches upon the phenomenon of sprawl (large conurbations with relatively low population density) as a result of increased mobility.

I earlier ruminated on what might happen to traffic fatalities in the midst of the swine flu epidemic (and noted the vast gulf between the numbers of deaths from both causes).

An answer of sorts has come from Mexico City, from Eric Britton over at World Streets. Via the newspaper Reforma, we learn:

Apparently the swine flu in Mexico City caused few real deaths but many traffic deaths. The large drop in the volume of cars increased velocities and also increased traffic fatalities. There were 12 traffic fatalities in the 6 days before the government issued their swine flu alert and 75 traffic fatalities in the 6 days after.

Here is the kicker: the increase in traffic deaths (63) dwarfs the number of swine flu deaths (8) during those six days.

This is hardly scientific, and I’m dubious increased speeds would be the main reason — I’d guess instead higher exposure from people avoiding public transit — but it is certainly suggestive.
