Today I learned F1 cars can have their engines blown up wirelessly via IP connection

We PC gamers often like to flirt with F1 driving, from sim racing to straight-up brand sponsorship and partnership. We tend to be a techy bunch, too. So I was a little angry at myself for not already knowing that, as Ex-F1 Senior Systems Engineer Dan «EngineMode11» explains, «An F1 car has an IP address.»

I mean, duh, of course F1 cars have IP addresses. Right? We're talking about some of the most sophisticated automobiles on the planet, designed to chop sharp turns at well over 100 mph and quickly climb back up to 200+ mph, all without spattering person across the asphalt.

If everyday dawdler vehicles are now packed to the brim with electronics, including wireless tech (and they are), you can bet that F1 cars are, too. And we already know that F1 teams like Alpine painstakingly gather shedloads of car sensor data for analysis. What, did we expect F1 cars to pit-stop-and-USB? 

No, much is done wirelessly, apparently using the F1 car's IP address. Or, to be more precise, using one of its multiple IP addresses, because, as Dan explains in a reply, «there are several depending on what you want to do.»

What you probably don't want to do is blow up the car's engine, though. And that, Dan implies, is something that might have actually happened. «The fear» about having an F1 car with an IP address, he explains, «isn't from external bad actors. It's internally, from the electronics team, who definitely wouldn't accidentally connect to the wrong car and flash the ECU of one running on the test bed instead of the sim, that's definitely never happened.»

An ECU, for reference, is a car's Electronic Control Unit, which controls much of its engine's systems, such as the ignition. Now, thankfully, I've never actually had anything go wrong when flashing a motherboard BIOS, which is why I'm not too fussed about doing so. If my motherboard was connected to a
