Buses have been around since the turn of the century. Specifically motor mass-produced buses since 1910 according to wikipedia. Now Rosa Parks did her famous civil action bit in 1955 of refusal to move. While others later appropriated the use of bus to drive change such as Freedom Riders and many others. Was Rosa Parks the first person to use bus to make a non-violent protest using bus as a prop or are/were there any others before her who used it in some different context ?
Similarly were Freedom Riders the first to use the bus to use it as a dialog or others had before no matter what the context.
I want to know if anything "interesting" happened between 1910 - 1955 which was not just about travelling, accidents or robberies/death etc. If not, then they would be the first ones to use buses in the manner that they did.
