> The above Wikipedia quote is also contradicted later in the same article, which says that a driver named Louis O’Regan died in 2024.
The list of fatalities is for on the Isle of Man TT Mountain Course which is used by both the Isle of Man TT races and Manx Grand Prix races (the "amateur rider's alternative" to the Island of Man TT). Louis O’Regan died qualifying for the Manx Grand Prix, meaning the 2024 Isle of Man TT was deathless. The list is confusingly combining two races for some reason.
