There is no reason a person should be driving while high. Period.
Sure it is your right to get high, but it is NOT your right to put others on the road in danger.
If there is not a good baseline for impairment for MJ then maybe a field sobriety test would be more appropriate.
the model shows 72 batteries. Probably 5200mAh 4 cell lipos. So yeah roughly $1600 in batteries. 36 ducted vans @ $145 a piece so $5220. 36 speed controllers @ $125/piece $4500. Then a control board So another $1-200 and the costs of the frame, so $100. And its going to be as aloud as hell...
There should be a page on the Powerchute software where you tell it when you changed the batteries. tell it you just changed the batteries and then run the self test. This might work. The batteries should not have died that quickly unless they were being depleted often.
YAY! I've loved my ATH-A900s ever since I had them imported like 4 years ago from Japan because Audio-technica hadn't brought them stateside. I actually bought them based off of recommendations from head-fi.org. They really are super comfy and sound good without needed an amp. Nice to see...
