AZ Lawmaker arrested: susp of ext dui
He came to the attention of police when “a state trooper spotted him driving with his right-side wheels on the shoulder of the road“.

Wrong-way driver arrested: DUI susp

DUI drivers remain a serious threat to every road user, whether you walk, or jog, or ride a bike or ride a motorcycle, or drive a car. SSTI recently published a good review of related research on the occasion of Utah being the first US state to lower per se limit to 0.05 BAC.
The latest gem is a driver who initially came to the attention of police when they “began receiving calls reporting a reckless driver in a Nissan Rogue traveling on the sidewalk and nearly striking several vehicles along Milton Road in Flagstaff.” Police stopped the vehicle but the driver fled, ending up going wrong way on I-40. This is on a Saturday (11/17/2018) afternoon around 3:30pm. Continue reading “Wrong-way driver arrested: DUI susp”
Public Safety Fee going into effect
This new and much-needed fee is the result of weak and/or duplicitous politicians who have neglected to honestly fund transportation in Arizona for decades; despite sporadic efforts that always fail in Arizona’s Republican-controlled legislature. They are so stridently, and uniformly ideological that they can’t even admit that gas tax revenue, because of the way it’s structured, have been going steadily down in real terms, for well over twenty years. The same is true at the federal level as well. Continue reading “Public Safety Fee going into effect”
Scottsdale (and now Tempe) regulates scooter/bike sharing companies

I can’t possibly keep up with all this… but just to point out, these regulations affect the companies; and have nothing to do with operation and rules of the road. The latest being Scottsdale:
Renting a bicycle or scooter in Old Town Scottsdale? Here are the new rules to know
In one oblique reference to rules-of-the-road, it mentions/claims “Renters can ride … scooters on sidewalks”; I don’t have time to unpack yet another set of local ordinances but I don’t see how that’s possible ; see e.g. here for Phoenix and Tempe operating ordinances.

Bicycle Friendly Delaware Act
The state of Delaware passed a package of updates to rules-of-the-road in 2017; as outlined by bikelaw.com
In October 2017, Delaware’s governor signed the Bicycle Friendly Delaware Act, placing into state law some cutting-edge, pro-bike reforms that put Delaware emphatically into a category of one among U.S. states when it comes to favorable statutory law treatment of cycling. The highlights:
1. requirement that drivers have to change lanes to pass;
2. the “Delaware Yield” at stop signs;
3. deletion of the “as far to the right as practicable” provision;
4. no aggressive honking at cyclists.

Suspect arrested in hit-and-run that injured deputy
This horrible incident occurred in Springfield Township, OH October 2018. I’m listing it here as a point of reference regarding hit-and-run and traffic justice. It’s also a good reminder that law enforcement officers face significant risks from dangerous drivers, compared to other occupations risks, e.g. bad guys with guns.

Toole Design explains why we don’t have bike lanes in the US
According to Toole, et al, were it not for Forester, we would now have bike lanes everywhere. And not just bike lanes, the entire US would look something like Utrecht, Copenhagen, or Amsterdam. The March 2018 article is a review of a paper by Bill Schultheiss, Rebecca Sanders, and Jennifer Toole of Toole Design Group :
A Brief History of How American Transportation Engineers Resisted Bike Lanes
The “VC is only for old white males” is a trope. John Forester, author of Effective Cycling reiterates, e.g. in this August 2018 discussion thread (group membership required to see whole thread): Continue reading “Toole Design explains why we don’t have bike lanes in the US”
Personal delivery device

Autonomous Deliver Robots were enabled in Arizona in 2018, and further re-vamped the law in 2020.
Side-note:This all reminded me of the pizza delivery robot in an episode of Black Mirror.
As of Sept 2025, Doordash says they are rolling out “Doordash dot” for testing.
Polar labs based in Tempe/Mesa have been testing for some time (?early to mid-2024. At the time I saw them, pictured right, they were still accompanied by a “chaperone” following on an ebike).
Polar Labs appears to be supplying doordash.
