RF and all the hacking I see in this domain are nothing short of fascinating. I will never trust my GPS watch again!<p>Further, imagine all the havoc one of these systems could bring. You could basically forge every Strava segment in your area to be at the top of the leader board. Heck, you don&#x27;t even have to be in the area. Go to a race and just slightly zap every device that runs&#x2F;cycles by. These are just the &quot;haha&quot;, non-life changing ideas. There are some really shitty ideas too...<p>Wow... hack all the things!
