Cops use new detector like radar for bike-buzzers

Did you know there’s a law in many states dictating how much passing space you need to give a bicyclist on the road? Wisconsin set the tone for the legislation back in 1973, and since then 33 states have added some kind of legislation of the books covering “Safe Passing,” 26 of which have set an actual minimum distance between the driver and the bike.

Up until now that has been a mere suggestion, since there’s been no real way to measure such offenses other than by eye. Codaxus LLC, an Austin-based startup has created an ultrasonic detector called Physics Package C3FT that mounts to bicycle handlebars expressly for the purpose of deducing passing distances. The detector itself sits on an adjustable arm and displays the distance measurement; sound and LEDs let the rider know when they’re too close.

There are different measurement modes; a continuous mode will show real-time distance measurements, while capture mode displays only the nearest measurement inside the set threshold, and the 3- and 6-foot Alarm mode triggers the buzzer and lights when someone buzzes the rider inside those thresholds. The setup can work in conjunction with a GoPro camera to record the display and the traffic.

The C3FT isn’t the kind of biking accessory the average person is likely to buy; it costs $1,400, which is more than the average bike you’re likely to see on the street. Codaxus points out that it’s likely to be of use to law enforcement, municipal planners, and researchers, but riders and drivers should know that it’s out there, ready to catch infractions. Citizen advocacy groups will likely want to use C3FT as well.

In fact, Friends of Outdoor Chattanooga, an outdoor activity advocacy group in Tennessee bought a device and donated it to the police department. The Chattanooga Police Department kicked off a Safe Bike Initiative in spring of 2015 in response to increased cycling in the area and the expected influx of even more cyclists for Ironman races in September and one that recently took place May 22.

The Safe Bike Initiative is being led by CPO Rob Simmons, who regularly takes the C3FT out for a spin. According to Simmons, drivers shouldn’t fear the mighty C3FT just yet. He said, “Our main goal is education.” He said most people know there’s some statute about passing, but not the specifics. He informs drivers and gives them a verbal warning. As with a lot of human interactions, attitude determines what actually happens — if they give him a hard time or don’t take the info he provides seriously, then he takes the next step and gives them a ticket. Breaking the city law will run a driver $120; ignoring the state law can cost a driver more than $200. By encouraging judges to order bicycle safety classes, Simmons shows he cares about affecting change rather than collecting fines.

Codaxus let Digital Trends know that another municipality near Tampa, Florida is the latest to grab a C3FT. New York, this writers home state, doesn’t have a legal definition of a “safe” distance but asks drivers overtaking from behind to pass to the left of bikes. New Jersey has no law protecting cyclists from being buzzed at all, but according to Christopher Stanton, co-founder of Codaxus, the times, they are a’changing: Ohio is another state that has no law protecting cyclists from being buzzed; the legislation was rejected as being impossible to enforce. Now that the C3FT exists it’s been added to the legislation, so it’s not only helpful to states that already have protective laws in place, but to those struggling to get statutes passed. Pennsylvania is the only state in the union with a 4 foot minimum passing distance, so be aware if you live in that state, commute through it, or are planning to visit.

Competitors question Trek’s claims about its new bike helmet tech
Trek Bontrager WaveCel Helmet

Last month, Trek and Bontrager unveiled a line of new cycling helmets that are reportedly a significant upgrade in terms of safety. In fact, according to Trek the helmets are 48 times more effective at preventing concussions as compared to traditional models using EPS foam to provide protection. These improvements come courtesy of a new technology known as WaveCel, which is said to be highly effective at absorbing and redirecting the energy that is created as a result of an impact.

It didn't take long for competitors to begin calling Trek's bold claims into question, however, with two companies that make competing helmet technology seemingly unimpressed. Both MIPS and Koroyd have published their own thoughts on what WaveCel brings to the table, with both saying it isn't a major upgrade over the tech that they've been using for some time.

Forget police helicopters, California cops are using drones to spot suspects

Here in 2019, drones are probably most associated with cool photography, drone racing, and the glittering promise of flying Amazon deliveries. But drones could have a role to play in law enforcement, too -- and a new report suggests that these aerial robocops have a bright future ahead of them.

In a pilot study carried out by California’s Chula Vista Police Department and drone cloud platform Cape, police drones contributed to 20 arrests over a three-month period. Starting in October, drones were used as part of a program called DFR, short for Drone as a First Response. This program dispatched drones on more than 282 flights, during which the UAVs racked up some 62 hours of total flight time. The goal was to see how drones could be employed to offer real-time aerial data to police officers.
