I was surprised at lighting system of the priority seats.
It's breakthrough for pregnants to let sitting passengers offer the seats without asking them.
Even if every passenger knows it would be better to offer seats for those who need priority seats,
chatting passengers or those who are devoted to watching smartphones can hardly notice if there are such passengers.
I wish transmitters for pregnants could be global standard to make the device usable in the other metro systems, if its lighting system expands to them.
