Motorcycle App Helps You Ride Faster, Turn Sharper, Brake Harder
Hugh Pickens writes "Alexander George writes about a new app that takes the data from a smartphone's accelerometers, GPS, and inclinometer to plot information for braking force, lean angles, speed, and on-track location onto Google Maps to shave precious milliseconds off each lap time in motorcycle races. Race Sense is designed to be a useful tool for someone who races for a living and a very fun toy for those who just like to brag about what lean angle they got at their ride day, and what top speed they reached down the main straight. Australian Grand Prix motorcycle road racer Anthony West provided much of the R&D that went into tweaking the app. 'With sponsorship's so hard to find and I need another way to survive. I spent some of my own money developing it with an Italian guy who also likes to ride himself, and who writes programs,' says West who designed Race Sense to fulfill the needs of a genuine MotoGP racer. 'Sometimes it's one second [separating] 20 people. If you adjust one little thing thinking about something in one corner you can lose four places.'"
Or it could save people by letting them realise just how awful their riding skills are, with some pointers to improve them. Watching people try to drive or ride on a twisty road shows you just how poor most of them are at picking lines, making corrections if required, and judging entry/exit speeds. This is supposed to be used on racetracks, which means the local fun roads will be tracked/mapped about 3 seconds later.
Smart phone apps don't kill people, reckless drivers kill people.
You can't look at your gauge cluster. It's too far out of view (racers don't sit on top of their bikes, they hang off the sides). Honestly, I don't know anyone that even looks at their tach. We have shift lights, but you can tell where you're at in the rev range based on sound and power delivery. And in the event you forget then your rev limiter will remind you. :-)
What some people don't know, or don't realize, is that at the track there's only one thing you are focusing on and that's the next turn. So you're fully aware of your velocity, where you need to brake, where you need your body, and where you need the bike. 99% of the time the only place you're looking is where you want to go, which is way out in front of your bike. And your bike is capable of a lot more than you are, so almost always your limiting factor is what you /think/ is the limit, so your gut gets tight and your butthole closes shut when you start to test your limits. Your brain will recognize if you're going into a turn 1mph faster than you have in the past and it will let you know in every way it knows how (more adrenaline, an "OH SHIT" feeling, total panic, whatever you're set up to do).
Whereas when you're driving on the road you're worried about paying a bill when you get home, or who let the DJ play that crappy song, or what a road sign up ahead says. You get lost in thought, you realize you don't remember the last kilometer of driving, or whatever. Not because you're bad drivers, just because the different circumstances give you a luxury of time.
