we feel inertia in bus,rickshaw in a good way (i mean BHALOBHABE
).but don't feel same in water vehicles.i had a chance to have a ride in ship.there i didn't feel inertia...again,(though i haven't got a ride on a plane) in plane people don't get inertia,while the plane is moving the quickest speed than the others stated.my teacher recently told me that now there are some trains which move with magnate and of course quick(i don't know the speed).here also people don't get inertia....
now what's the secret????
