Time to destination - 20 minutes from any point to any other point in San Antonio. Almost, anyway. Other drivers - Usually polite. Not particularly attentive. Willing to assist, if you are in trouble. Typically drive trucks, suburbans or utility vehicles. Acceleration - Very gradual, but keeps going until eventually at or over the speed limit. Speed limits - Most of us obey the posted speed limit. Many of us will go even slower. Just in case. Often under 10 mph or more below the limit. Suburbs that are their own towns are speed traps. Beware. Most of the time we will not warn you of a speed trap by flashing our lights either. First speeding ticket of the year: ask for defensive driving school. Second: ask for deferred adjudication. Beer and booze - Legal limit: 0.08% blood alcohol content, minors - anything greater than zero. Not allowed to drink while driving anymore, not even passengers. Distances no longer measured in six packs. Passing - Left lane is for passing only. Just kidding. Some of us will take being passed (or if you merge in front of them) personally and will proceed to chase you and try to cut you off as payback. Turns - We don't follow the dashed lines provided for our convenience and instead slice the turn often resulting in swinging into the adjacent lane afterwards. Must come to a near stop before executing a turn. An old joke: a blinking turn signal means it was that way when the owner picked up the car at the dealership. Actually not true anymore. We are improving fast with our signaling. Entering a road - We may pull out of a parking lot or a side street without any consideration for traffic. If there is more than one lane, we may do it directly into the far lane. With the sole exception of entering a freeway, we don't merge, even if there is a separate acceleration lane provided for it. We will stop at the start of the lane and wait for the second coming of the prophet Zarquon. Changing lanes - We don't change lanes unless absolutely necessary. We'd rather stop in front of an obstacle, or trail behind a bicycle, rather than go around it. If a lane change is required, it must be done at the earliest possible opportunity, even if it means stopping first to do it. The default lane of choice: left, of course. Speed bumps - Must stop first and crawl over the bump, even if the bump is designated to be taken at 20 mph with a large yellow sign. Speed bumps may be a form of cancer. They keep multiplying and none is ever removed. Full steam ahead and damn the shock absorbers! Parking lots - We must make up our mind as to which parking spot to take before entering the parking lot. If it means blocking traffic for a minute or two on the street, so be it. If a lot is full, we will drive excruciatingly slowly looking for the miracle spot. During this time we will ignore all rules of the road. Most of the time you will not be able to drive between two adjacent parking lots, so pick your entrance carefully. Ramps - Must slow down. Entering a freeway - no exception. Mobile phones - Yes. As if we weren't distracted enough already. Rain - Everyone will slow down. A lot. In all lanes. Everyone must stop before crossing a puddle. Snow or ice - Very rare. When it happens, we have no clue and pile up all over the place. Avoid driving. I mean it. Horn - Not to be used under any circumstances.
