Ha, I'd still say it's possible for people to believe (say, >75% probability) that self-driving cars will come in the next five years AND have a good reason not to take you up on the bet. Namely, in the event they lose the bet they NOT ONLY (a) don't get to enjoy self-driving cars, (b) don't see a return on whatever time/financial investment they made into the technology and (c) lose $1000 to you, but they also (d) are publicly embarrassed on your website.
