I actually rode in a "Reddy Killowatt" electric car with my dad,it was a promotional car from an electric company that the gas & electric company he worked for used as a meter reader / utility vehicle ..
This was around 1970,I was about 12 years old..
He drove it in a parade in our hometown,the person who was supposed to drive it was ill ,so my dad was chosen to fill in for him..
We made it about 3 miles,but when we went to turn off the main street out of the parade route after some warning lights indicating a "low battery charge" came,on,we only made it about halfway up a steep hill about 1/4 mile long,and we sat there awhile,and the batteries recovered enough to turn it around and go back down the hill,and we made it back to the electric company plant site by using an alternate route,which included going down a few one way streets the wrong way..we crawled into the parking lot going about 5 mph..

..
My dad wasn't too impressed with the thing,it had a big sticker on the back saying "car of the future" if I remember right..he said "I really hope its NOT what we'll be driving around in years to come!..
I actually found a company newsletter / magazine the gas & electric company published monthly that had a picture of us in the car in the parade..however ,I went searching for it more than once and can't find it now,dammit..
