Very good ideas. Could be improved upon thus:

• seat belt and window cutter for your key ring - always present, in the bus, train, other peoples cars.

• Practice emergency procedures. To be actually able to perform them under stress.

• Always carry a compact emergency kit with band-aid and one or two pads. Possibly a rescue blanket in your backpack.

• Always have some cash handy (may depend on your country, municipality).
