Perhaps, but one of the current trade-offs one must make when designing the power system of an EV relates to deep-discharge (for fast acceleration) versus slow-discharge (for longer travel time) battery technology. Use enough Aerogel's and the choice can swing in favour of the longer life slow-discharge batteries; the caps provide the periodic quick-discharge with the added bonus of charging MUCH faster than deep-discharge batteries. Obviously you wouldn't be able to sustain the acceleration, just buffer the sharp spikes related to "pedal-to-metal" acceleration and regeneratively braking/decelerating to the caps.
