VNicco wrote this rough draft. He wants to revise the draft to include evidence from a credible source.

Young drivers should be required to hold a provisional driver’s license for one year before earning full driving privileges. Provisional licenses have restrictions on the number of passengers allowed in the car. Provisional licenses also restrict the number of hours that drivers can be on the road. These restrictions save lives because newly licensed drivers need time to become comfortable on the road.

Which phrase would provide the most credible evidence?

Data revealed on the public announcement channel shows that fewer accidents occur among drivers who held provisional licenses.
The sales team at Voyage Autos prefer to sell to clients who have held provisional licenses.
Many parents of new drivers have real concerns about their teens driving home from school events that take place in the evening.
Messages found in chat rooms often quote young drivers who have shared their driving experiences with one another.
