Early race cars were not paragons of safety. I don't think I'd go so far as to say that Chapman intentionally made his cars less safe to make them faster, but I also don't know that he'd have spent any weight budget to make them safer than the regulations required.
IE
"if it's possible to make a winning car win by having the wheels fall off of it as it crosses the finish lines" -- that's okay
VS
"If it's possible to make a winning car win by having the wheels fall off of it as it crosses the finish line, then it bursts into flame and kills the driver" -- that's probably no okay.
But there's a lot of grey area between the two, and that's where winning teams won (and occasionally lost drivers / spectators). Old time car racing was blood sport.
They were death traps, racing drivers were way more cautious back in those days because any slightly severe accident was likely to result in death or severe injuries. Reliability was garbage too so basically just crossing the finish line was a great result.
I think having recently been through WW2 where "reasonable things" included tasks like "hey let's disarm this unexploded bomb by chilling it in liquid oxygen." fundamentally altered people's risk calculus for a generation or two.
I mainly talking about driving styles, modern F1 drivers pull all kinds of maneuvers and drive so close to the limit that would be totally suicidal back in those days (especially for overtaking, you aren't going to fight as hard when you know that any crash might result in death or severe injury)
Of course a lot of that is because of the cars. 50s to 60s cars had basically no downforce and would be undriveable on modern tracks amongst other things.
I'm certainly not implying that modern drivers are less risk-averse these days, just that the risks were massively higher and drivers generally took that into account.
