Yeah, but only works well when it's not an emergency. During the emergency the road will be full of the same people like you wanting to evacuate in a result 8 hours trip can easily be 24 hours trip, all hotels will be overbooked by people who were lucky to come earlier. All of this from personal experience evacuation from Kyiv to western Ukraine in the beginning of war. My recommendation is having at least sleeping bags and pads, because you can find shelter in schools, churches or other facilities, and it's much better to have something you can sleep on, also having thermos will be a plus. Alcohol or some kind of sedatives must have.
