The key is that if your design goals are ambitious but achievable then you end up with a killer product. If your design goals are unrealistic or unachievable you tank what's achievable chasing a dream. Being frank the difference is probably that Steve Jobs had 30 years being a hands on expert in his field, and this guy was just some bloke who fancied building a self driving car.

All too often I've seen people set design goals when they don't understand the underlying problem. If jobs had targeted building an iPod that was physically smaller than the current smallest hard disk available he'd have been in this position.
