Personal Mobility: Not Done Cookin'
Earlier this month, Toyota unveiled its i-unit prototype, which is essentially a very tiny car for one person.
For now, personal transportation devices may be a "hammer in search of a nail." They don't fit elegantly into our lives, either culturally or geographically. From an engineering perspective, these devices are exciting and innovative. But with a few exceptions, they aren't very useful to us yet.
Perhaps there may come a culture shift whereby personal mobility will play a critical role. Communities would have to be built with these devices in mind, including infrastructure and legal considerations; retirement villages would be a good proving ground for these. Energy shortages may nudge us toward accepting personal transportation devices, but while the principles behind them are sound, we simply aren't ready for them.
