The Better Place model addresses the problems of slow recharging, and in so doing works to eliminate the concern of long-distance travelers who may find themselves far from home with a dead battery. It just requires battery packs to be standardized across vehicle manufacturers - good luck with that in the absence of government regulation.
The Better Place model does nothing - nothing - to resolve the problem of huge battery pack cost. A Bentley is expensive if one leases it or buys it.
Toyota and Honda figured this out long ago. Use of small battery packs to improve efficiency (their hybrids) makes a lot more sense than pure electric vehicles.
