I have wanted to get into an EV and it is the long distance travel issue (for that 1% of the time) that has been keeping me (and I imagine a lot of people) from making the switch. Tesla is the only model to have come close to solving that issue.
One thing I have been waiting to see is a push to have gas stations adopt EV charging on a large scale. Gas stations, particularly ones along interstate routes, often double as rest stops and usually have large parking areas with small marts, and a couple of fast food options. If companies partnered with a major gas pump operator like chevron, shell or mobile to offer even a small number of charging stations with each gas station (even just 2 to 4 at each site in the 50-100kw range.. though the wiring would most likely need to be upgraded to support this) things would shift rapidly I think. I know charge times remain an issue, but if you are taking a rest stop anyway.. the 30-40 minutes of charge is not as big of an issue.
A government subsidy could also be introduced to help offset some of the cost of upgrading these gas stations. An increased tax on Gasoline could go towards paying for such a subsidy. Also I think we need to take another look at nuclear power to help charge those EVs, but that is another conversation.
