I'm an EV customer, in a cold climate, far from the Tesla factory and the smooth roads of the Bay Area in California USA. So I've had some experience of the reality of working with this new tech.
Let's do the future-perfect exercise. Let's imagine looking backward from a point in history when 90% of new vehicle sales (by unit) are EVs.
What happened in those years?
1) power cells (the component parts of batteries) became genuine microelectronic parts with fine structure in their insides -- deep submillimeter gaps between anodes and cathodes. That understanding about their manufacture put their cost-per-watt on a Moore's Law kind of curve about nine years ago.
2) vehicles routinely get field upgrades to their battery packs.
3) there's major competition between battery remanufacturing plants and stationary power storage makers for the used battery packs, complete with spam and robocalls begging for the old batteries.
4) the power grid companies, in every US state except Wyoming, have now integrated their distribution systems so there's distributed control over time-shiftable load. In other words, EVs have grid smarts in them and charge when the spot price per kWh is lowest in their neighborhood. It's an auctioning service.
5) in Wyoming there's a pirate electricity auctioning service available via encrypted wireless and Tor to work around the pro-coal lobby's laws.
6) truck stops, everywhere except Wyoming, now have megawatt-level charging facilities. Trucks don't use I-80 to get across the Continental Divide any more.
7) Public housing projects have been compellled to offer EV charging. Apartments without EV charging facilities are now considered substandard. Their slumlords have to discount them at least $200 per month (in 2017) dollars to find tenants.
8) An open standard -- called "STREETNET" -- for vehicle-to-vehicle communication has developed with multiple communication channels. An important channel is modulation in brake-light and running-light intensity. That means a vehicle can announce its status to the vehicle behind it.
9) STREETNET has virtually eliminated compression-wave congestion on limited access highways, by helping drivers and autodrive systems see the big picture and synchronize their speeds and acceleration.
10) Commuter rail is all electric and autodriving, and has been for five years.
- lootsauce 9y agoLove the brake light idea, simple solution. A radio signal would be one of many, the one directly in front of you needing to be differentiated from the one behind or to the side or on a side street requiring a much more complicated system and protocol that might never be agreed upon and be expensive to implement for retrofitting legacy cars. It makes up for in simplicity what it lacks in features and that could really drive adoption.
- OliverJones 9y agoYeah, combined with short range radio you could get a useful system. The lights would announce the sender's vehicle ID (new random number each trip for privacy) and speed / acceleration / whatever from three or four vehicles up front. The radio could announce more detailed vehicle-id-tagged information. A car's receiver can easily filter out unknown vehicle ids. Random vehicle IDs are probably vital to acceptance.
