One of the weaknesses of Electric cars is that they take longer to refuel than a petrol burning car. One of the advantages of electric cars is that they take longer to refuel than a petrol burning car. For some people this is a deal breaker. They don’t want to be forced to wait from two to 12 hours for their car to charge. I think that this could be a strength of electric cars.

While I was cat sitting I spent time playing with a Roomba. Most people set the roomba, and let it clean. I don’t. I watch it and I observe how it works, how it goes from place to place and how it navigates, and gets trapped, and procrastinates in one corner or part of an apartment/studio. Roombas are glamourised but I think they are flawed. Their flaw is that they start from their dock, back and go beep beep beep beep, then they rotate and they start cleaning.
