The Driverless Car

Sebastian Thrun helped build Google's amazing driverless car, powered by a very personal quest to save lives and reduce traffic accidents. Jawdropping video shows the DARPA Challenge-winning car motoring through busy city traffic with no one behind the wheel, and dramatic test drive footage from TED2011 demonstrates how fast the thing can really go.

Tapescript cloze

As a boy, I loved cars. When I turned 18, I lost my best friend ___ a car accident. Like this. And then I decided I'd dedicate my life to saving one million people every year. Now I haven't succeeded, so this is just a progress report, but I'm here to tell you a little bit about self-driving cars.  

I saw the concept first in the DARPA Grand Challenges _____ the U.S. government issued a prize to build a self-driving car that could navigate a desert. And even though a hundred teams were there, these cars went nowhere. So we decided at Stanford to build a different self-driving car. We built the hardware and the software. We made it learn from us, and we ____ it free in the desert. And the unimaginable happened: it became the first car to ____ return from a DARPA Grand Challenge, winning Stanford 2 million dollars. ____ I still hadn't saved a single life.  

Since, our work has focused on building driving cars that can drive ________ by themselves -- any street in California. We've driven 140,000 miles. Our cars have sensors by _____ they magically can see everything around them and make decisions about every ______ of driving. It's the perfect driving mechanism. We've driven in cities, like in San Francisco here. We've driven from San Francisco to Los Angeles on Highway 1.  

We've encountered joggers, busy highways, toll booths, and this is ________ a person in the loop; the car just drives itself. In fact, while we drove 140,000 miles, people didn't _____ notice. Mountain roads, day and night, and even crooked Lombard Street in San Francisco. Sometimes our cars get so crazy, they even ___ little stunts.  

Now I can't get my friend Harold back to life, but I ____ do something for all the people who died. Do you know that driving accidents are the number one cause of death for young people? And do you realize that almost all of those are ____ to human error and not machine error, and can _________ be prevented by machines?  

Do you realize that we could change the capacity of highways by a factor of two or three if we didn't rely on human precision on staying in the lane - improve body position and therefore drive a little bit closer together on a little bit narrower lanes, and do _____ with all traffic jams on highways? Do you realize that you, TED users, spend an average of 52 minutes per day in traffic, wasting your time on your daily commute? You could ______ this time. This is four billion hours wasted in this country ______. And it's 2.4 billion gallons of gasoline wasted.  

Now I think there's a vision here, a new technology, and I'm really looking forward to a time when generations _____ us look back at us and say how ridiculous it was that humans were driving cars.

Can you explain why the verb tenses are not appropriate or wrong?
