the same pattern with decent bike batteries, the second and subsequent generations seem to last well and have few early failures
cheap ones still fail rapidly but gradually or worse fail suddenly in upsetting ways (see cheap bikes and "custom kits" to "upgrade"cheap bikes, scooters and suchlike have similar problems at the bottom end of the market) such as exploding while charging and with some tweaked ones pulling enough current to explode in use
first gen bus batteries were a bit burny compared to those of a decade later, they often held less energy than was required for the day and often less than it said on the specs
of the 4 first gen batteries, one failed in infancy, 2 of the others were still 70%+ viable after ten years and the other was down to about 35% stated capacity(the bikes had multiple age/hard use issues)
the modern ones are about ten yrs old and as good as new for practical purposes
car and large batteries have been in the gen two specs for a while, the new ones are far better for kwh per kilo, long lasting(longer than the structure and mechanicals of a hard used vehicle) and have far less firey chemistry
battery reliability and safety is no longer an issue with decent quality manufacture, cheap*carp will always be troublesome be it an ev or equadorean hair curling tongs, not us a colleague of tt's, saved £100+, plugged em in, applied normal fire fighting procedures and threw the blazing mass out of a window  i had the good sense to use my £12, electric, 20" PISSA PAN, with added comedy user manual for humorous effect and never plugged it in
the manual has gems such as "place thumb over intimate orifice while cleaning, otherwise the unit may be out of service or on fire" and other wise advice
*(or expensive carp, several models of lambos and porches have a slightly dubious rep for being upside down and on fire  )
re ev batteries, the recent responsibly made ones seem reliable and safe, the emerging ones are reliable safe and have a lot more kwh/k |

sometimes an off-road vehicle does need to be big for assorted reasons, leccy is better than gallons per mile muscle blocks to give motive power for off-road(and the bits on roads)
ps if you are going fast enough and have front/sump armour, vertical clearance is less of a problem than other things
no suv is ideal for urban
some are better than others if the road is less than tidy or safe, ditto many dedicated off-road machines which often have one small problem that is special to them, like being upside down or looking for a rare breakable spare in the wilds or not being good with mudsandrocksslopes or whatever
as to a vehicle to get there, wherever there may be, many of the best are not huge or power hungry or marketed for the job off the line, some need few adaptations apart from driving style
same chances as ice that with EVs some of the "reasonably priced" "family/ trade" "general purpose" runabouts are pretty good off-road even without tweaks
until folk try RP ev cars in the real world we do not know which might be ideal for "rugged"
tis odd where a fiesta, panda or transit can go with a bit of care older vehicles are available as examples
i could go on about off-road bikes of various sorts
big and powerful is horrid, agile and easy to control is ideal
"can i pick me and it up if needs be?"
off road, not heavier than you and what you need to shift is optimal
for me a Czech 125 and me and a half me of climbing tat for load wt went places some would find more than a challenging walk
and was more reliable in a blizzard over Shap than the big Norton in a start together, one retired sort of way
a honda C90 is rather good on squelchy or lumpy and can jump, that jump thing surprised me as well
assorted evs will turn out to have surprising abilities that make cruder but deliberate ones redundant
darwin applies to evolving tech as well as to lifeforms
whatever the style or requirements, EV gets my vote, good ones or disappointing ones are both good, this part of the process towards no ice is the same as buggy to ice, carp will fail and useful will thrive
if the producers provide lots of ev styles, a few will work well, but not always the way they were marketed
some will be ace in rough circumstances for rp vehicles sold for "domestic needs" even without tweaks
the big and deliberate hare is often beaten by an accidental tortoise off-road |
