What a ridiculous comment from your fellow passenger!
Many ATC facilities will instruct pilots to “line up and wait”, meaning to enter the runway, face the direction of takeoff (normally upwind) and stop the aircraft.
Many pilots will also need time to calculate or confirm departure performance (we have a lot to bear in mind! Weight and balance, takeoff velocities, power settings, SID/departure clearance, autopilot procedure/configuration, post departure communications and the potential for an aborted takeoff or an engine failure after takeoff!) - I would go as far to say a good pilot will stop and evaluate all data and information before sending several thousand tons of metal filled with hundreds of people down a concrete strip with the purpose of generating enough lift to move the aircraft into flight, as opposed to mindlessly sending a plane into the air without hesitation.
I suppose on the railway similar principles apply - a good driver will wait for a few seconds, recall the PSR, ensure there are no TSR/ESR’s in place, double check the signal, check the next scheduled stop and ensure full understanding before applying power to commit to a fully safe departure
To me, a good driver is one who has such a thorough level of route and traction knowledge that they’re not only able to get the train there safely, but know how to apply power and braking to maximise passenger comfort throughout.
