1. Ice cream trucks. I have narrowly missed crushing children twice near where I live. Stopped about 2 meters short in each case. My 10 year DMV record is empty. There is also the 2 or 3 times women have blocked half the road at the illegal day care centr. Just as I give up and pass, short child in back seat opens door and gets out into the only remaining open lane. 3 more narrow misses. Total of 5. Adding a tonnne of of dead weight to a vehicle will significantly increase the number of crushed humans.
A. Due to the quietness of the EV it is unknown whether EVs will cause more accidents or not. Due to their weight it is also unknown whether severity of accidents will be higher or lower.
2. Catalina. Houses on Catalina island have a parking place for a golf-cart type vehicle. All such vehicles I saw were gasoline powered. Batteries will not climb the hills around Avalon. Next trip, see for yourself
A. EVs can easily be made more powerful than gas cars. Most locomotives and largest of mining trucks use electric power.

3. Glendale College. There is a steep hill from the main campas to the parking lot. I can almost keep up with the electric vehicle used to haul people up the hill.
A. Just use a bigger electric motor.
4. Drag racing. While maximum performance electric vehicles can go 0 to 100 in 5 seconds or so, engine powered vehicles do 0 to 325 in the same length of time. Still a signifant performance gap.
A. An electric dragracer can easily beat any gas car on the strip. And you wont have to worry about destroying the engine.
5. Efficiency. Batteries under heavy draw recover about 1/2 the charging energy under heavy draw. Gasoline engines (burning hydrogen perhaps) recover 1/4 the "charging energy" Trouble is that an aluminum gasoline car will weigh half as much as the battery vehicle, thus both consume roughly the same equivalent amount of fuel. There is also #1 above.
An electric Honda Prius consumes 250 W-Hr per mile. If you cover an acre with PV cells you can drive 6,000,000 miles a year off the power. While biodiesel you would only be able to drive 1,500 miles off the same acre.
6. Resources. Most battery vehicles use exotic materials that require significant energy to produce. It takes about a decade to breakeven on energy or money when buying a hybrid subcompact versus the non-hybrid version of the same vehicle. I used an aluminum car analysis to get this number. Also the hybrid is heaver. See #1 above.
To build an eletric car you need far fewer parts and it would be cheaper to build overall. Electric Motor, charge controller, and a battery thats about it. The battery is recycled.
7. Maintenance. Most of these cars, even the hybrid are low-production units. Co-worker had a (then new design) car with a CVT (transmission in it). When transmission started wearing out, auto shop got transmission on ground and then said: "we can not fix this" No parts available, even from dealer. Dealer offered a new transmission
A. There is no virtually no maintenence on an electric car. No oil changes, no tune ups, no smog checks, a brushless electric motor will never wear out and if it does it will cost to rplace as mush as a wet-dry vac at home depot, $50.
8. Fuel cells have to be at 80 Centigrade to work. Tough to fly in to LAX and expect to drive to Bakerfields if the car sat in the airport parking for a week.
A. Fuel cells are hydrogen are a joke imho. To make hydrogen you can either use fossil fuels or electricity. If you use electricity, you can make hydrogen for about $2 gas equilivent.
9. Two cars required. At present, battery cars actually have an advantage in urban settings. Too bad most Americans live in the suburbs. Most "Renewable energy" (AKA useless) energy options require tearing down most of the existing housing stock so we can live in urban centers like San Francisco. It also helps to make dogs illegal. Otherwise two cars are needed to drive one on the freeway and the other on short trips. That requires insurance, parking, and depriciation. Each car cost about the same as each dog, about $8k/year. The real estate lady's dog needs a heart valve or $15k.
