Can family court hopefully modify custody and visitation of a man who has two tickets of serious careless driving crashes in 5 days?

The issue is safety and well being of the woman's son. She was never notified of his accidents and one of the accidents took place on a visitation weekend. The boy was not in the car but he very well could have been. They were accidents that rendered both vehicles he was driving inoperable, one may be damaged beyond repair, his own, and the other was a rental. He totaled the car in front of him and pushed it into the car in front of that one with the rental, the second accident. The first one was with his car that may have been totaled, his. The second has a witness to say he was completely inattentive. All three are suing. All accidents were his fault and was ticketed. The car he is driving now has safety issues, like a faulty blower with windows fogging up when driving and one or more inoperable windows, leaks oil, and probably a lot more. It does not have ABS. Not clean diesel, an 83 Mercedes, no real radio either. What can the mother do with this information in the legal system?
