Will it only be for a lower class because of affordability or will there be a market for compact affordable electric cars.Which begs this question...Would you buy a gas station, jiffy lube or any other commercial property that caters to petroleum based cars?

Make sure you budget for time, consultations, removal, root raking, in-fill, soil testing, compaction testing, and tree replacement costs. 

Purchase price: $196 Cash invested: $50,000 A compact two-family house with one 1 bed/1 bath apartment and one 2 bed/2 bath apartment and a small backyard.

Was it compacted?

Especially with what they pulled up from the line.True story:  toilet clog, found the cause was a toothbrush inside the toilet. 

Debris must be compacted and fill dirt must be compacted,  you don't want a sinkhole in your yard. 

@Jeff Cliff if it is an in ground pool this is not the job for a handyman and will likely cost $5-7k because you need to make sure you break up the bottom of the pool to ensure proper drainage, demolish the decking and fill compactly. 

Maybe a hairbrush or toothbrush if the house hasn't been cleaned out?

Re:SS most people will not become able to be self supporting in retirement, so having paid into SS over a lifetime is a good hedge plus its part of our compact as a society.  

I don’t think indoor pools will be a good idea unless it is some multi million dollar estate or those expensive deals in NY city.I had to remove the bottom of the pool to allow drainage and then back filled with approved soil with compaction reports and geologist oversight and stamped approvals.
