You do need to be able to stop and i do find using acc alot (as i do) the car brakes alot more than i would. The brake regen is imo to wear them down more, so you need to service them more often and they make more money from us.
Coz look imo once a car is in motion one should be able to create free energy from the movement of air and all you would really need is a battery to help start the car and get it moving again.. a fully self rechargeable hybrid. Not these fake ones that got two engines a turbine or many turbines. No need to plug in or recharge.
I do think there is tech out there that is surpressed as it will open up free endless fuel for us the consumer but what good is that to the powers in charge. Very intresting though When i was alot younger i used to go deep inside the hydro electric power plant in snowdonia with my dad as they had a skip way down like 1.5 miles down and it intrested me then hydro elctric power and they use part of the energy created to pump the water back to the top of the mountain to do it all again.. That was 3o+ years ago.
