The weird and poor ergonomic bus design these day also partly to blame. U see many buses inside now got floor height tall and low, a small misstep at a wrong place could cause serious injury liao. The seat arrangement also very weird. Some seats could even put u in a dangerous position; imagine if the bus driver did a hard brake, your whole body could just fly forward 扑街. That's why they have seat belt at the last row of seat in some buses but then who uses it?Nowadays the bus drivers driving is horrible. Hard braking.
