With due respect. Activities generally involve some danger. Being a free individual allows us to decide what maybe dangerous or not.
Countless activities can be considered dangerous. Media stories that generate the most ad revenue rule though.
As far as motorcycles safer, yes, depending on the bike, I specifically upgraded bought a new bike in 2014 with Linked ABS brakes, many others have all sorts of multi point traction control. ABS is fantastic on a motorcycle, many times a reaction is to panic and not properly apply the brakes, its perfectly understandable on a bike, as its a balancing act between front and rear which are independent of each other.
With due respect, I've lead an exceptionally dangerous or adventurous life. There are acceptable or necessary risks, and then there are frivolous unnecessary risks. MC riding is the latter. Go watch motorcycle accident videos or aftermath. Most were survivable in a car. In fact, as stated, MCs are massively more risky, having huge solo accident fatalities cars rarely have.
Bikes are as stated earlier 18x greater fatality. Even deducting for single vehicle and drunk driving errors, which appear to be 4 out of 10, that's still 6 out of 10 involving 2nd vehicles and/or sober operators. Just looking at the latter categories, that's still about 10x more lethal than a passenger car.
And, let's also factor that car drivers just get in the car and go, whereas most (smart) bikers are wearing some PPE which usually entails leathers and helmet, and still result in a 10x or more fatality rate. So even with PPE, bikes are enormously more risky.
As I mentioned, the safety advances in bikes, are vastly eclipsed by cars. You mention better braking and handling on a newer bike as safety advances. I'll grant that. Cars have that, plus front, side, curtain airbags, crumple zones, side impact steel reinforced areas, roll cage or passenger area steel reinforcements, shatter resistant glass, anti-roll suspension features, plus the drivers are not exposed to elements, thrown objects, bugs, rocks, or have exposed limbs, seatbelts to protect from being thrown from the vehicle (very high fatality when thrown), head restraints to prevent whiplash, etc. Plus, balancing is not an issue but on bikes on windy days or roadway problems (grooves, obstacles, etc.) balance and tipping/dumping is a thing that cars don't worry as much about. Hitting a tire or branch in the road is a nuisance in a car, but could be death on a bike.
The risks I've taken, and there have been aplenty, were calculated and unavoidable and as safe as practical. Riding an MC, in my humble view, is simply foolishly pointlessly dangerous. A low speed T-bone with a texting teen, and you might be an amputee or suffer a serious TBI, or dead. I've seen videos where the bikes are obliterated and the biker in several pieces and the car barely damaged, and occupants physically fine.
