This is true as a general rule - the usual simple analogy that is Very commonly used is that of a car (earth) driving along at speed and bugs - the majority or really all the of the bugs are gonna splatter on the front windshield and front of the car of course, I dont think I have ever seen bugs splatter on the rear window!
Serious scientific Meteor observing/counting is a lot more complicated than you would think at first.
For example - Take these so called Taurids. There really are a 'shower' that goes on all year called the antehelions - this taken from Robert Lunsford's AMS page
http://www.amsmeteors.org/lunsford/
"The Anthelion radiant is now centered at 03:56 (059) +20. This area of the sky is located in central Taurus, five degrees southeast of the Pleiades (Seven Sisters) open star cluster. Since this radiant is large and diffuse, any slow to medium speed meteor from eastern Aries or Taurus could be a candidate for this shower. The center of this area is best placed near 0100 local standard time when it lies on the meridian and is highest in the sky. At this time of year the normal anthelion activity is combined with material from comet 2P Encke, producing the highest anthelion activity of the year. Rates should be near four per hour from the Northern Hemisphere and three per hour for observers south of the equator. With an entry velocity of 30 km/sec., the average anthelion meteor would be of medium-slow speed.
Unlike most of the annual showers the antihelion source is produced by debris from unknown objects orbiting in a direct motion like the earth. These objects are most likely asteroids, which produce stony and metallic debris whose density is much greater than material produced by comets. There is also the possibility that some of this activity may be caused by the “Jupiter family of comets”, comets which have been altered by Jupiter’s gravity into much shorter orbits. This material collides with the earth on the inbound portion of its orbit, before its closest approach to the sun. Therefore we best see them just after midnight when we are facing the direction from which this activity appears. The antihelion source is active all year from an area of the sky nearly opposite that of the sun. The center of this source will move approximately one degree eastward per day and travels through many different constellations over the course of a year. It may make sense to list these meteors as anthelions or "ANT" but a majority of meteor organizations prefer that you list them from the constellation in which the radiant is currently located or the constellation where the shower reaches maximum activity. Those who send their reports to the International Meteor Organization (IMO) should list these meteors as Southern (STA) or Northern Taurids (NTA), depending on whether the meteors radiate from south or north of the ecliptic."
So therefore the best activity for this 'shower' is mostly around midnight - 1am - not the very early morning hours so much which is the usual norm of course. A classic possible example of an ANT was Rowena's awesome meteor shot (taken at around 11pm local time) last oct
Rowena's meteor
One also has to very careful not to include sporadics (the mongrels or mutts of the serious meteor observers world) in with the pedigree poodles (ordained meteor shower members) hehe - well thats how it apears to me after 5-6 years of closely following 'meteorobs' list.
RL states in his current page "Sporadic rates seen from the Southern Hemisphere have reached a minimum and will slowly rise during the remainder of the year. From south of the equator one would expect to see approximately six random meteors per hour during the morning hours and two per hour during the evening."
The speed of the meteor is a HUGE determining factor as to wether the fireball or meteor you have seen could be a member of a known and studied shower, as well as other factors like colour, starting distance from radiant, distance travelled. So you can see that proper scientific meteor observing is much more complicated than people would think possibly. But that doesnt mean you cant just enjoy the show

- but you must be very careful about what you say is a definite shower member.
