In this clip from Industry Focus: Tech, Motley Fool analyst Dylan Lewis and contributor Daniel Sparks explain what we know about Apple's interest in self-driving cars. Also, they discuss what investors need to keep in mind when looking at this new and exciting space.

Dylan Lewis: If you had any doubts about Apple's interest in making self-driving cars, I think Tim Cook has been pretty coy in some public interviews about not really letting in on a lot of details, being a little cagey, the company sent a letter to the National Highway Traffic Safety Administration regarding Federal Automated Vehicle Policy earlier this month. And it made it pretty clear they have something cooking there. The NHTSA can grant exemptions to certain compliance standards if that organization decides that it's important for research and investigations. Apple's letter was essentially urging the administration to expedite the exemption requests that are coming in from some new entrants, so, some people that maybe haven't been quite as ambitious as the early entrants into autonomous driving. That, I think, says all you need to hear about their interest in this space, and the fact that it's something that they're obviously putting a decent number of resources into.

Daniel Sparks: Yeah, I think that Apple is definitely working on a car, as far as we can tell. Recent reports suggest that the company has hundreds of employees working on it. The transition, initially, it was referred to as Project Titan, and it initially transitioned away from building a car -- this is all speculation, keep in mind -- to really focusing on the technology, similar to Alphabet. The rumor is, now, it's going to be deeply integrated into iOS, and the company is looking for a 2017 deadline of proof of concept of something that can work. So, Alphabet and Apple, these are still really speculative things. But, at least with Alphabet, we're starting to see a direction, an actual company, and an effort to monetize the business, which is encouraging. 

Lewis: And for both of those companies, these are things that are exciting. They're very attractive, they're fun to speculate on because they are nascent tech. But they are not going to be meaningful to the top line or bottom line for quite some time. That's something to keep in mind there.
