Am I alone in thinking that truck driving is an arduous job that ideally shouldn't be done by humans at all?
* long hours and days spent in loneliness, away from family and friends,
* possibility to stretch and move your body is very limited,
* bad hyper-processed food, hence so many drivers are obese,
* the need of humans to sleep and relax means that the trucks cannot legally move for majority of the day, thus there is a need to have more of them,
* plus, as mentioned here, both the drivers and their managers are incentivized to break and bend the law, resulting in unsafe driving.
All of the above would be mitigated by robots taking the wheel.
