The Morgan driver is clearly at fault, however the Peugeot driver was sounding his/her horn for a fairly long period and if they were hard on the brakes they should have easily come to a near standstill from 50.
Conclusion is they were doing considerably more than 50, and/or not fully applying the brakes, or not able to react correctly because of lack of talent/distraction/whatever.
Its the Morgan driver's fault, but the Peugeot driver is displaying a typical lack of road craft also.
