> An engineer friend spends all his spare time tweaking an electric motorcycle. There's a lot to control in software
While an electric motorcycle might have a fairly simple ECU, something like my Mustang is a bit more complex. While software and hardware to modify the ECU coding yourself is available, as well as the training for it, most in the community highly advise against DIY and paying a pro (which most of us do) to do it for you. $200 to let someone who "knows" what their doing vs 1 wrong value and you blow a rod or crack the block...

It would probably turn into the same discussion I have with friends as to why I'm more comfortable doing electrical work in a house, vs doing plumbing work. I've accepted the risk that if I get electrocuted, it's just me being screwed, vs if I screw up a plumbing solder, I can flood an entire house. With gasoline, I know what precautions to take and avoid an explosion. Vs the voltage / amperage on a tesla style battery pack, yeah, check it with a volt meter and make sure everything is grounded properly - but accidents will still occur.
There are precautions to take on both sides; there's new education on both sides; etc... More than anything, maybe it just falls to nostalgia; working on cars with dad made me work on cars when I got older. I'm not opposed to electric cars - I quite welcome them as a fact - I have a step son who wants to be a diesel engineer mechanic and I told him, may all well find classes for electric motors and get into that / get a head start (hes 15). As dad got me into cars, maybe my step son gets me into electric motors...
