Car on car: At 70mph (my interstate's posted speed in the USA) or 112 kph the chance of dying is about 50%. FWIW this is actually pretty hard to verify with direct studies/data after researching.
For every 10 mph of increased speed, the risk of dying in a crash doubles. In addition, as your speed increases so does your risk of serious injuries and damage to vehicles and property. In fact, speed accounted for approximately one-third of all traffic deaths in 2018, totaling 9,378 deaths.
= Car on pedestrian: A healthy adult has a 50% chance of dying when getting hit 70 kph or ~45mph. At 55mph, it's basically 80%. Many studies confirm this.
So it's more like: you have a pretty high chance of dying when you get hit by a car as a pedestrian.
But what are the chances of getting hit by a car? Sure, lots of people die every year due to car accidents, but what is the chance that it's actually you getting hit.
Nah. I just haven't slept that well since I took 1.1g of 5-HTP. Don't do that. The "high" isn't worth the stomach pain, throwing up and insomnia. The barely existing but definitely existing visuals are pretty cool though.
I mean 5-Hydroxytryptophan, the serotonin precursor. It wasn't really a "trip" and more like blurry vision and very mild drifting, similar to LSD or MDMA. It definitely was there and wasn't just there because I wanted it to have an effect. It literally just highers your serotonin production, but not MDMA does.
I probably just had a light overdose and light serotonin syndrome or something like that. Should've stayed with 0.9g
