That is a pretty far off base conclusion, the goal is to make roads feel unsafe for drivers so they go slower, and reduce or eliminate commute distance, that is how roads are made safer.
For example, a common strategy is to narrow a road from 4 lanes to 2 with a center median, being either a turn lane, planter with half height jersey barrier (directs cars wheels back onto the roadway), or barrels filled with water (which absorbs impacts and makes roads much safer). Tactics like these make roads feel more claustrophobic and thus "dangerous", but the road is ultimately much safer in the event of an accident, and accidents are less likely due to drivers being more alert because of the narrow roadway.
TL;DR: Wide roads lull you into a false sense of safety, narrow them!
