Re: You don't need self-driving to get into trouble
"As any motorcyclist will tell you the problem is really anti-lock brakes on modern cars...."
This motorcyclist is telling you it's not just ABS, it's all brakes. For every single car, even with the shittiest brakes, if you stomp on them the brakes lock and the car skids. What this tells you is that the limiting condition for optimal braking isn't the power of the brakes, it's the friction between tyre and road, which is proportional to the tyre surface area. For cars, you don't only have 2 more tyres, you have each tyre, having at least 5X the contact area as a bike tyre (since bike tyres are rounded, even quite fat bike tyres don't have that large of a surface area). Most of a bikes' stopping power is anyway on the front wheel, which is usually skinnier. So a car that weighs around 6 times a bike+rider has at least 10X stopping power. Pretty much any car can stop faster than pretty much any bike. This information is critical for bikers to realise that they need to leave a bigger gap to the car in front than if they were driving a car. Unfortunately quite a few bikers don't know and/or respect that.
On acceleration it's different, it's only quite powerful cars / bikes that have so much power that it's more than the tyre traction can handle, resulting in wheelspin (or traction control kicking in). The limit on acceleration is usually engine power vs mass, not traction available. Even small-ish bikes have engine powers of at least half that of a quite normal car, but with around 6X less mass
Re lane splitting, even where it's allowed, I only do it when traffic is very slow or stopped, and even then keep a safe speed differential and have to always be very aware of cars trying to change lanes without warning. In normal driving, drive to one side of the preceding car, so your tyres are running behind theirs. This allows the option of steering past if you can't brake on time. Plus, many roads are built so that if there are any manholes or other irregularities they are in the middle of the lane (where cars would go over them without touching), so driving a bit to one side will also avoid these extra bumps.
