It seems to be a bit of a dangerous catch-22 situation when it comes to driving while baked.
If you're new to weed, new to driving, or new to driving while stoned, I'd strongly advise against it.
On the other hand, I've found after a couple of years of driving stoned at least a couple of times a week, I have no problem with it.
Once you're experienced with weed, driving, and the combination of the two, it seems to be extremely easy - and certainly a lot safer than driving drunk.
The only time it gets stressful is when you have a car full of stoned people who chatter and giggle continuously. That can be distracting. Passengers: if your driver is also stoned, please don't try to explain to them your concept of a neverending cycle of death and rebirth of the universe.
