I have just spent the last 3 days & 2000+ km criss-crossing Germany in a car with technology I have never seen before … and would never want to travel without again. This was a standard, off the show room model with just one (standard) extra. It had Radar.
Let me explain.
The car had forward looking radar that was connected to the cruise control. The driver would set a desired speed and then also a ‘follow zone’ from any car in front. For the driver this is just selecting 1-5 as a follow option. The ‘follow zone’ was not a set distance but some formula about speed. eg at a slow speed you would follow closer, but at a higher speed there would be a greater safe space. When it rained the follow distance would increase to account for the conditions
So you jump on a German Autobahn with Cruise set at 180 kmph & the radar is looking forward 150 meters. When the car detects another vehicle in front of it, the car will automatically slow down to reach the designated follow distance. When that vehicle moves out of the way the car will automatically accelerate to reach your set cruise speed.
If you come into a sharp corner the car sees the road via Sat-Nav & will slow you down to a safe cornering speed even when there is no traffic ahead.
Over the 3 days we had every possible motorway traffic condition (apart from snow & ice). We also did a fair bit of town & country driving. Read more »
