I don't have ABS though i don't particularly miss it, only had one emergency braking event, stay calm enough to not lock the front, and still calm enough to perform cadence braking on the rear when it locked up.
I think most people these days start in cars/bikes with all these electronic safety features, which is great that they exist but few take the time to understand how to control their vehicles properly without those safety features.
I agree most people don't take the time to understand how to control their vehicles properly and I'm sure many people with the features haven't explored the full or correct way to use them.
None of the bikes I've been through had ABS, same for the bikes I've had a chance to ride. What I do know is at any moment the traction that you have when breaking in an emergency or even in general can change.
Like having that brake dialed in perfect to make the emergency stop for accident that you can see is about to happen in front of you, only then seeing your going to have to cross that smooth painted white line to a void the prang while you are breaking and pumped on adrenaline.
The car that just jumped the robot and your already in the intersection, realizing the car that you just avoided was leaking oil and now you are letting off the breaks and opening up but it feels like you are ice skating.
To round that obscure bend you know and do everyday to work, as you come over that lip you find out they have dug up for fiber and the roads covered in fresh tossed gravel, you are coming up after the round and have 5 to 7 meters to the stop sign.
In those moments I believe the safety features will give you a better chance and if I were in a position to get a new bike it would at least have ABS.
I've been riding a long time and I've had rear lockups (sometimes quite fun), I've had front lockups (NOT fun) and have both lockup at the same time (a change of pants is normally required in the figurative and sometimes literal sense followed by seeing a doctor of some kind), I've had my crashes, spills and thrills and after all those years I'm still learning.
The biggest safety feature for any one on a motorbike, on a scooter and in a car is the one between their ears.
