What is the primary danger when driving a tracked excavator (excavadora sobre orugas) across hard concrete or asphalt roads?

1. Steel tracks have very low friction on hard paved surfaces and can slide uncontrollably on even slight slopes, while steel grousers severely gouge and destroy the public road asphalt
2. The tracks will melt instantly from friction
3. The engine will turn into an electric motor
4. The hydraulic oil boils immediately
