dr. avent, please proceed. welcome. >> mr. chairman, members of the subcommittee, thank you for the opportunity to address you today on this very important topic. as many of you know, the vision of driverless cars has been around well over 50 years, but very little progress was made in that area until 2004, which d a arpa created a prize competition called the darpa grand challenge. since then, there's an exponential growth in the underlying av technology that mirrors the development trajectories in other markets. today, i'd like to briefly touch on three dimensions of connected and autonomous vehicles. as you all pointed out, numerous papers abound, outlining the promises of autonomous vehicles. if developed correctly, the primary advantage of autonomous vehicles centers on significantly lowering driver-related deaths. as you pointed out, senator, last year alone, there were nearly 40,000 fatalities in the u.s. at a cost of over $410 billion. and more than 90% of those were due to human error.
