I started my journey at the Cadillac House, drove out of the city and got on the 1-95 toward Washington, D.C.. It’s about a four-hour drive.
As soon as I jumped on the highway, I sped up to about 70 miles per hour and entered standard cruise control. A small indicator on the instrument panel(仪表盘) showed the car was ready to engage self-driving mode. I pushed a button on the steering wheel to begin, initiating Super Cruise mode.
A green light bar at the top of my steering wheel showed that Super Cruise was on. There were no shake, no sudden speed changes or anything like that. The car remained perfectly steady. It uses a combination of cameras, radar sensors, and GPS to find the center of the lane. The car found it like a train on a track.
I had to admit that I was little worried about letting the car take over at first. I kept my hands near the wheel and my eyes locked on the road. After about ten minutes, I finally started to trust the car’s judgment. It soon became clear that it could easily drive itself in light traffic, braking when necessary and keeping a steady speed.
Then we hit a bottleneck. There was a standstill traffic outside of Baltimore, and things could have easily gone wrong, but this is where Super Cruise really shined. The vehicle came to a complete stop to avoid crashing into traffic, then sped up when cars started moving again. It was impressive as well, and something that sets the 2018 Cadillac CT6 apart from all competitors.
I eventually turned off the highway and headed into Washington D.C.. To turn Super Cruise of, I simply hit the button on the steering wheel again. The green light at the top of the wheel turned off, and I took control of the car.
The CT6 had no problem bringing me from New York to Washington, D.C, in Super Cruise mode practically all by itself. It makes me hopeful for a future where I’ll never need to touch a steering wheel again.
