@40hz:
Then we have something in common, regarding to the accident I mean. In my situation replace the pickup truck for a truck that was carrying 30.000 liters of milk. Luckily seconds before impact I saw the accident coming so I lay my head and as much of my body against the steering wheel for damage control. My neck did not get a "full" whiplash, but was also not the same after-wards.
But hey, when my neck gets warm I don't have any troubles falling asleep.
Ok, on-topic again:
I wonder how far you could get on a battery charge. As the construction does not have (too) much weight to push around, my guesstimate would be 2 or 3 miles?
