Final answer:
The true way to assist a fatigued driver is by ensuring they take adequate breaks and get proper rest, not just through smaller batteries or more frequent charging stops for electric vehicles.
Step-by-step explanation:
The only true way to help a fatigued driver is to ensure they take regular breaks and get adequate rest. Driving while fatigued can be as dangerous as driving under the influence of alcohol or drugs because it impairs reaction time, judgment, and decision-making. Employing strategies such as smaller batteries and more frequent charging stops could apply to commercial electric trucks, where reduced battery size could mean less weight and potentially less fatigue over long distances. However, when it comes to driver fatigue, this type of strategy does not directly address the issue. Instead, drivers should stop and rest when they feel tired, and trucking companies might consider systems such as forklift-loaded pre-charged battery modules to minimize vehicle downtime, allowing for driver breaks during battery swapping.
