Speed choice and driving performance in simulated foggy conditions

▶ Lane keeping abilities tend to remain robust to all but the most severe fog densities. ▶ Drivers appear to be willing to drive at high speeds while driving in fog. ▶ Fog does not appear to limit drivers' ability to maintain proper lane position. ▶ Speed choice appears to be driven by factors beyond speed perception in fog. ▶ Further research describing behavioral changes associated with fog is warranted.
