No. It is actually much safer than an automatic transmission if the person who drives it actually knows that WTF is doing it. The problem and the reason why they are statistically "more dangerous" is that idiots who have no idea get them because they are (only marginally) cheaper and more concerned with "switching" and controlling the vehicle have to concentrate.
When a person who knows what they are doing drives a manual, they actually have more control over the vehicle and are much safer to drive.
Here are some examples that support my point of view:
1. Tractor units have only been in series production since 2012 and are on the move with automatic transmissions. Almost all of them are now automatic transmissions, and a situation arises where truck drivers cannot be trusted when Semi were ALL manuals. A. Tractor trailer was the vehicle to follow and be in traffic because it was guaranteed that they knew what they were doing and that (about 20 years ago) they were (mostly) the safest vehicles on the road. Truck drivers were really professional drivers 20 years ago. Now that almost all trucks are automatic transmissions, every idiot drives them. And if you didn't notice, even most truck drivers on the road are now idiots you can't be safe in traffic with.
The reason for this is the same reason why all "self-driving" features that vehicles have today have allowed stupid people to believe that they are not responsible; They assume that they can blame an accident that "this sensor has not triggered".
"My automatic braking was not activated."
"The cruise control didn't work properly, so I left it behind. I was on my phone. That's why mom and her three children are dead. My car's computer has broken down."
Eff these excuses. The driver is responsible.
2. Many manufacturers of all vehicles since 2016 even hesitate to offer a manual transmission option because people suck at it, don't know what they're doing, and newer generations are lazy and just want to get out and press buttons and pedals and treat driving like one video game.
* Very terrible in my opinion. I support the idea that ALL vehicles should be manuals without power steering or other supporting "devices" like today's vehicles have. Newer vehicles make the streets much less safe than they can be because they allow thoughtless, careless, selfish, ignorant (lack of knowledge; people who have no idea how to drive) to take control of a £ 3,000 death weapon gain.
Cars shouldn't drive themselves. The driver should drive it. The reason "manuals are more dangerous" is not the actual mechanics and design of the vehicle. This is because of the (idiotic and ignorant or lazy and selfish) people who drive them.
Because of laziness and ignorance (how the word "ignorant" is defined: lack of skills or knowledge, laziness), technology has made people not only manual transmissions, but also many other things less common and more dangerous.
A person who actually knows how to drive a manual transmission does not have to focus on the clutch pedal and shifting. It is natural for them.
