Just my personal experience but on the question of motorcycles and safety here,
you need full awareness and the determination not to take risks.
Virtually all the motorbike riders here take far far too many obviously dangerous risks. Weaving in and out of traffic with just inches to spare is just inviting an accident IMHO
Overtaking and undertaking with clearly visible oncoming traffic is another no brainer.

There's really no protection on a bike other than defensive driving. Which the majority of motorbike drivers do not do.
Well actually most drivers on the road are too aggressive.

It has been mentioned that in this tragic accident some of the students had already asked the drive to slow down and be careful.
Not saying it was the driver to blame, but so many drivers of passenger vehicles are just not trained.
So many vehicles in public transportation are not adequately maintained/serviced either.
