That is complete and utter bollocks. The figures a couple of pages back go to show that the number of deaths on the roads in 2018 (1,784) was more than five times the number on the railways even if you include suicides. If you don't it's more than forty times, and that still includes people doing daft things at level crossings, despite lights, barriers and the rest of it.
What you are effectively arguing here is that we should ignore hundreds of preventable deaths on the roads each year and spend untold millions of pounds on motion sensors, cameras and the rest of it to prevent - probably - a couple of dozen deaths on the railway. Are you for real?!
