If you think careful driving and awareness increase your safety, you are deeply mistaken.
Lucky amulets hanging from the rear view mirror, Bangkok, Thailand
Some simple protective measures (medallions, amulets, statues of deities) are fully sufficient.
Just hang it all on your mirror, and you're set. Which is probably why so many Thais drive quite recklessly, especially on their motorbikes.
With this many protection, nothing can possibly harm the driver or the car, isn't that right?
