Key legal question
Whether the tailgating constituted a serious traffic violation requiring a minimum three-month license withdrawal.
Extracted holding
Yes. The driver's conduct created an acute danger and amounted to a serious violation under Art. 16c SVG, so the minimum three-month withdrawal applied.
Extracted reasoning
A 10-meter gap at about 100 km/h over several hundred meters was clearly insufficient; the danger was serious regardless of the vehicle's safety systems. At least gross negligence was present.
