Garmin is a high-end manufacturer of GPS devices for bicycles and motor vehicles.
Garmin has posted an ad for a cycling “radar” (probably actually LEDdar using pulsed infrared light), which warns cyclists of overtaking traffic. There are some serious problems with the product concept and with the ad, so once you’ve viewed the ad, please read on.
The $200 Garmin device, an accessory for a bicycle GPS unit which costs several hundreds of dollars, informs the cyclist that a vehicle is about to overtake. But in order to decide what to do about that, the cyclist needs to know how much clearance the vehicle will give. The Garmin device doesn’t provide that information.
The stilted British voice in the ad conveys an air of authority, I suppose, but how is the cyclist in the ad not going to HEAR the huge truck approaching from behind? Unless the cyclist is listening to something at top volume on headphones — but I didn’t see any. The cyclist never once is shown looking back, and he isn’t using a mirror, and so what is the device supposed to let him know that he wouldn’t know anyway? Granted, the device could give a warning of a quiet car.
The “cyclist’s eye view” clip in the video shows his response to the warning: pulling over to the right edge of the roadway, so far that grass would be brushing his right foot and he risks a fall on the cracked pavement — which could turn a brush-by into a fatal.
Imagine what a nuisance this device would be when being passed by strings of vehicles. It would give a continuous warning, which would provide no useful information. One more good reason to use my $15 rear-view mirror to check on overtaking traffic, and use my cell phone for GPS (no extra cost) and forget Garmin!
The ad repeats the figure from a League of American Bicyclist survey of fatal bicycle crashes, that 40% are in overtaking crashes. That widely publicized number has several problems though:
- First of all, there are more problems with the numbers. My friend Patricia Kovacs comments:
LAB’s Every Bicyclist Counts study found 40% of bike fatalities were hit from behind. I’ve been studying crash data in Ohio and in 2015, 30% of bike fatalities were hit from behind. But not all hit from behind are the motorist’s fault. In Ohio, 15 out of 24 fatal bike crashes were the fault of the cyclist, 6 were the fault of the motorist and 3 were no error, according to the police officers’ reports. What were the circumstances for the cyclists at fault? Improper crossing, not visible, failure to yield, lying or illegally in roadway. Most of these circumstances can be mitigated with education. I do worry about drunk and distracted drivers though, which is why I use a mirror.
- The LAB study is biased in covering only fatal collisions, which are rare. Just as an example, in the over 100 million miles of travel in the 50-year history of the bicycle club to which I belong, approximately 1000 lifetimes of riding for an avid cyclist, there have been only two fatalities to club members. One was a rear-ender and the other was a head-on collision with an out-of-control vehicle that crossed to the wrong side of the road. Non-fatal crashes are hundreds of times as common and result in far more loss of years of useful life. 3/4 of serious bicycle crashes don’t involve a motor vehicle at all.
- The League puts forward the 40% figure to promote its support for barrier-separated bikeways in urban areas, but fatal overtaking crashes occur mostly on rural roads. Most urban fatalities result from crossing and turning movements.
Half-truths have been used repeatedly to sell cycling infrastructure (as with the League’s study) but Garmin’s is the most sophisticated use of half-truths I’ve seen so far to sell a cycling product, while also being seriously ill-informed.
