Точно така. От линка на асахи става ясно че от 2011, производителите са длъжни да вграждат DRL в автомобилите си. A грешката в новия ни закон е че не се прави разлика между DRL и фаровеи ги постава под един знаменател
.
Асахи, понеже държиш на официалната литература, ето ти малко за четене относно негативните ефекти от карането с DRL директно от pdf на сайта на EU. Текстът е малко дълъг, но изключително интересен.

"1.2 Possible Adverse effects of DRL
Given those hypothetical working mechanisms of DRL there also may be adverse effects.
1.2.1. Adverse effects of DRL due to a higher conspicuity
If DRL is assumed to increase the conspicuity of a vehicle with DRL, road users without DRL will
become less conspicuous. It may be impossible to render a vehicle more conspicuous by means of
7DRL and at the same time keep other road users without DRL at the same conspicuity level.
Conspicuity is not an absolute measure and is determined by both object and the background. As
noted conspicuity of vehicles in daytime is strongly dependent on the extent of pattern 'competition'
provided by the background (see e.g. Henderson et al., 1983). Lab studies have shown that the most
conspicuous object may grab attention (Theeuwes, 1991, 1992) and possibly may even capture the
eyes of the observer (see. e.g., Theeuwes, Kramer, Hahn, & Irwin, 1998).
A special concern with DRL and its effect on conspicuity is related to motorcyclists. In many
countries motorcycles are required or advised to use running lights during daytime. Motorcyclists
use DRL because without headlamps they are relatively inconspicuous given their size, contour and
colour. If motorcyclists are conspicuous during daytime because currently they are the only road
users that use DRL, it is likely that once DRL is mandatory for all road users, motorcyclists become
less conspicuous. Thus, given the definition of conspicuity it is to be expected that a motorcyclist
with headlamps is less likely to be detected when all other vehicles have headlamps than when only
the motorcyclist has headlamps.
1.2.2. Adverse effects of DRL due to a consistent search feature
Search for a possible vehicle with DRL can be fast because attention can be selectively tuned to
one specific feature, that is, objects with lights. Even though this may be beneficial for road users
with DRL it may have negative consequences for road users that do not have DRL. In laboratory
studies (see, e.g., Theeuwes, 1990), it was shown that when attention is selectively tuned to a
specific feature, the other - even highly conspicuous features - are completely neglected. For the
traffic environment this might imply that road users who do not have DRL (pedestrians, cyclists,
car without DRL) might not only be missed because they have a relatively low conspicuity but
also because they are not coded as possible targets. As noted by Hörberg and Rumar (1979)
‘compared with vehicles using lights, vehicles without lights will be more difficult to detect’ (p.
172). It is argued that because drivers may adopt a different strategy for car detection from the
one they normally use during daylight, for example, the presence of two lights rather than the
appearance of a vehicle shape, vehicles without lights would be less 'visible' than if no vehicle
displayed lights under these conditions. Hence, because DRL provides a consistent feature for
the driver's search strategy, all vehicles without two headlights could have a lower detection
probability than vehicles equipped with DRL.
1.2.3. Adverse effects of DRL due to a feature for identification
As noted DRL can work as a fast and accurate feature for identification. Road users with DRL are
relevant for the driving task. Given these mechanisms, adverse effects are likely. Fast and accurate
identification of road users having DRL could be traded off with a slow and erroneous identification
8of road users without DRL. In this respect, an erroneous identification implies that the object is
fixated but not recognised as a possible target. These errors are likely for identification of
pedestrians, cyclists and especially for cars without DRL (i.e., when DRL is gradually
implemented)."

а цитатите ми са от Wikipedia, от статията за DRL и са обосновани с официална литература, индексирана под текста.![[smilie11]](https://photo-forum.net/forum/smileys/smilie11.gif)
И нали уж DRL сме ги въвеждали били заради дебилите дето карат без фарове по здрач... Ми то какво излиза, DRL не DRL, пак вечер го гасиш и пускаш фаровете по собствена преценка. Ами сега? ![[smilie7]](https://photo-forum.net/forum/smileys/smilie7.gif)
