Short Term Memory Loss from Bike Crash Filled in with GPS Data



[NYT] A cyclists in California got into an accident and almost had no recollection of the incident. He was going downhill at about 30 miles per hour. And somehow ended up with a broken nose, concussion, road rash, stitches to the face, and a deep cut to the knee for good measure.

He was riding along and lost about 20 minutes of his memory. He really wanted to know how and why he crashed. He didn’t even remember if he passed out before the crash – causing the crash. Well good thing he was using a (helmet of course) GPS cycling computer which was recording his speed, location, pedal rate, and heart rate. It is almost like a black box.

This rider was using a Garmin 305 which you can pick up for less than $200. It lets you upload your track details to a Web service, and have you show off your stats to other riders. Luckily his Garmin 305 was not harmed. He uploaded the data to his computer. He could clearly see before his crash his speed went from 30mph to 10mph while his heart rate remained at 126bpm (at least it wasn’t heart attack?). Of course he also overlayed the data onto Google Maps to figure out the exact location of the accident.

Just before where the GPS said he crashed, he could sure enough see a long, thin, deep pothole which was even visible in Google’s street view. He also happened to find one of his lenses from his glasses that he broke…
