When dealing with true geniuses, you always have to bring your A-game. When you're right, it's definitely possible that a fellow intelligent person will see the merit in your idea and will implement it, or improve upon it, in some way.
But if you're wrong, they'll often have no problem telling you that they differ in opinion or perspective.
And when it comes to brilliant minds in tech, it doesn't get much bigger, better, or revolutionary than Elon Musk.
When this guy tweeted at Musk asking for a standard speedometer in the upcoming Tesla Model 3 all-electric car, Musk offered this terse reply.
If he comes off a bit rude, he's not the only visionary who's been known to be rough around the edges.
The Model 3 will retail for $35,000 (around $42k for an optioned out one) before any government incentives or rebates, and it'll be available in limited supply for early adopters in July of 2017. It'll be outfitted with the same autopilot technology as the Model S and X.
